📰 Question: A historian of science studying Kepler’s laws discovers a polynomial with roots at $ \sqrt{1 + i} $ and $ \sqrt{1 - i} $. Construct the monic quadratic polynomial with real coefficients whose roots are these two complex numbers. 📰 Solution: Let $ \alpha = \sqrt{1 + i} $, $ \beta = \sqrt{1 - i} $. The conjugate pairs $ \alpha $ and $ -\alpha $, $ \beta $ and $ -\beta $ must both be roots for real coefficients, but since the polynomial is monic of degree 2 and has only these two specified roots, we must consider symmetry. Instead, compute the sum and product. Note $ (1 + i) + (1 - i) = 2 $, and $ (1 + i)(1 - i) = 1 + 1 = 2 $. Let $ z^2 - ( \alpha + \beta )z + \alpha\beta $. But observing that $ \alpha\beta = \sqrt{(1+i)(1-i)} = \sqrt{2} $. Also, $ \alpha^2 + \beta^2 = 2 $, and $ \alpha^2\beta^2 = 2 $. Let $ s = \alpha + \beta $. Then $ s^2 = \alpha^2 + \beta^2 + 2\alpha\beta = 2 + 2\sqrt{2} $. But to find a real polynomial, consider that $ \alpha = \sqrt{1+i} $, and $ \sqrt{1+i} = \sqrt{\sqrt{2}} e^{i\pi/8} = 2^{1/4} (\cos \frac{\pi}{8} + i\sin \frac{\pi}{8}) $. However, instead of direct polar form, consider squaring the sum. Alternatively, note that $ \alpha $ and $ \beta $ are conjugate-like in structure. But realize: $ \sqrt{1+i} $ and $ \sqrt{1-i} $ are not conjugates, but if we form a polynomial with both, and require real coefficients, then the minimal monic polynomial must have roots $ \sqrt{1+i}, -\sqrt{1+i}, \sqrt{1-i}, -\sqrt{1-i} $ unless paired. But the problem says "roots at" these two, so assume $ \alpha = \sqrt{1+i} $, $ \beta = \sqrt{1-i} $, and for real coefficients, must include $ -\alpha, -\beta $, but that gives four roots. Therefore, likely the polynomial has roots $ \sqrt{1+i} $ and $ \sqrt{1-i} $, and since coefficients are real, it must be invariant under conjugation. But $ \overline{\sqrt{1+i}} = \sqrt{1 - i} = \beta $, so if $ \alpha = \sqrt{1+i} $, then $ \overline{\alpha} = \beta $. Thus, the roots are $ \alpha $ and $ \overline{\alpha} $, so the monic quadratic is $ (z - \alpha)(z - \overline{\alpha}) = z^2 - 2\operatorname{Re}(\alpha) z + |\alpha|^2 $. Now $ \alpha^2 = 1+i $, so $ |\alpha|^2 = |\alpha^2| = |1+i| = \sqrt{2} $. Also, $ 2\operatorname{Re}(\alpha) = \alpha + \overline{\alpha} $. But $ (\alpha + \overline{\alpha})^2 = \alpha^2 + 2|\alpha|^2 + \overline{\alpha}^2 $? Wait: better: $ \operatorname{Re}(\alpha) = \frac{ \alpha + \overline{\alpha} }{2} $. From $ \alpha^2 = 1+i $, take real part: $ \operatorname{Re}(\alpha^2) = \operatorname{Re}(1+i) = 1 = |\alpha|^2 \cos(2\theta) $, $ \operatorname{Im}(\alpha^2) = \sin(2\theta) = 1 $. So $ \cos(2\theta) = 1/\sqrt{2} $, $ \sin(2\theta) = 1/\sqrt{2} $, so $ 2\theta = \pi/4 $, $ \theta = \pi/8 $. Then $ \operatorname{Re}(\alpha) = |\alpha| \cos\theta = \sqrt{2} \cos(\pi/8) $. But $ \cos(\pi/8) = \sqrt{2 + \sqrt{2}} / 2 $, so $ \operatorname{Re}(\alpha) = \sqrt{2} \cdot \frac{ \sqrt{2 + \sqrt{2}} }{2} = \frac{ \sqrt{2} \sqrt{2 + \sqrt{2}} }{2} $. This is messy. Instead, use identity: $ \alpha^2 = 1+i $, so $ \alpha^4 = (1+i)^2 = 2i $. But for the polynomial $ (z - \alpha)(z - \beta) = z^2 - (\alpha + \beta)z + \alpha\beta $. Note $ \alpha\beta = \sqrt{(1+i)(1-i)} = \sqrt{2} $. Now $ (\alpha + \beta)^2 = \alpha^2 + \beta^2 + 2\alpha\beta = (1+i) + (1-i) + 2\sqrt{2} = 2 + 2\sqrt{2} $. So $ \alpha + \beta = \sqrt{2 + 2\sqrt{2}} $? But this is not helpful. Note: $ \alpha $ and $ \beta $ satisfy a polynomial whose coefficients are symmetric. But recall: the minimal monic polynomial with real coefficients having $ \sqrt{1+i} $ as a root must also have $ -\sqrt{1+i} $, unless we accept complex coefficients, but we want real. So likely, the intended polynomial is formed by squaring: suppose $ z = \sqrt{1+i} $, then $ z^2 - 1 = i $, so $ (z^2 - 1)^2 = -1 $, so $ z^4 - 2z^2 + 1 = -1 \Rightarrow z^4 - 2z^2 + 2 = 0 $. But this has roots $ \pm\sqrt{1+i}, \pm\sqrt{1-i} $? Check: if $ z^2 = 1+i $, $ z^4 - 2z^2 + 2 = (1+i)^2 - 2(1+i) + 2 = 1+2i-1 -2 -2i + 2 = (0) + (2i - 2i) + (0) = 0? Wait: $ (1+i)^2 = 1 + 2i -1 = 2i $, then $ 2i - 2(1+i) + 2 = 2i -2 -2i + 2 = 0 $. Yes! So $ z^4 - 2z^2 + 2 = 0 $ has roots $ \pm\sqrt{1+i}, \pm\sqrt{1-i} $. But the problem wants a quadratic. However, if we take $ z = \sqrt{1+i} $ and $ -\sqrt{1-i} $, no. But notice: the root $ \sqrt{1+i} $, and its negative is also a root if polynomial is even, but $ f(-z) = f(z) $ only if symmetric. But $ f(z) = z^2 - 1 - i $ has $ \sqrt{1+i} $, but not symmetric. The minimal real-coefficient polynomial with $ \sqrt{1+i} $ as root is degree 4, but the problem likely intends the monic quadratic formed by $ \sqrt{1+i} $ and its conjugate $ \sqrt{1-i} $, even though it doesn't have real coefficients unless paired. But $ \sqrt{1-i} $ is not $ -\overline{\sqrt{1+i}} $. Let $ \alpha = \sqrt{1+i} $, $ \overline{\alpha} = \sqrt{1-i} $ since $ \overline{\sqrt{1+i}} = \sqrt{1-\overline{i}} = \sqrt{1-i} $. Yes! Complex conjugation commutes with square root? Only if domain is fixed. But $ \overline{\sqrt{z}} = \sqrt{\overline{z}} $ for $ \overline{z} $ in domain of definition. Assuming $ \sqrt{1+i} $ is taken with positive real part, then $ \overline{\sqrt{1+i}} = \sqrt{1-i} $. So the conjugate is $ \sqrt{1-i} = \overline{\alpha} $. So for a polynomial with real coefficients, if $ \alpha $ is a root, so is $ \overline{\alpha} $. So the roots are $ \sqrt{1+i} $ and $ \sqrt{1-i} = \overline{\sqrt{1+i}} $. Therefore, the monic quadratic is $ (z - \sqrt{1+i})(z - \overline{\sqrt{1+i}}) = z^2 - 2\operatorname{Re}(\sqrt{1+i}) z + |\sqrt{1+i}|^2 $. Now $ |\sqrt{1+i}|^2 = |\alpha|^2 = |1+i| = \sqrt{2} $? No: $ |\alpha|^2 = |\alpha^2| = |1+i| = \sqrt{2} $? No: $ |\alpha|^2 = | \alpha^2 |^{1} $? No: $ |\alpha^2| = |\alpha|^2 $, and $ \alpha^2 = 1+i $, so $ |\alpha|^2 = |1+i| = \sqrt{1^2 + 1^2} = \sqrt{2} $. Yes. And $ \operatorname{Re}(\alpha) = \frac{ \alpha + \overline{\alpha} }{2} $. From $ \alpha^2 = 1+i $, take modulus: $ |\alpha|^4 = |1+i|^2 = 2 $, so $ (|\alpha|^2)^2 = 2 $, thus $ |\alpha|^4 = 2 $, so $ |\alpha|^2 = \sqrt{2} $ (since magnitude positive). So $ \operatorname{Re}(\alpha) = \frac{ \alpha + \overline{\alpha} }{2} $. But $ (\alpha + \overline{\alpha})^2 = \alpha^2 + 2|\alpha|^2 + \overline{\alpha}^2 $? No: $ \overline{\alpha}^2 = \overline{\alpha^2} = \overline{1+i} = 1-i $. So $ (\alpha + \overline{\alpha})^2 = \alpha^2 + 2\alpha\overline{\alpha} + \overline{\alpha}^2 = (1+i) + (1-i) + 2|\alpha|^2 = 2 + 2\sqrt{2} $. Therefore, $ \alpha + \overline{\alpha} = \sqrt{2 + 2\sqrt{2}} $. So the quadratic is $ z^2 - \sqrt{2 + 2\sqrt{2}} \, z + \sqrt{2} $. But this is not nice. Wait — there's a better way: note that $ \sqrt{1+i} = \frac{\sqrt{2}}{2}(1+i)^{1/2} $, but perhaps the intended answer is to use the identity: the polynomial whose roots are $ \sqrt{1\pm i} $ is $ z^4 - 2z^2 + 2 = 0 $, but we want quadratic. But the only monic quadratic with real coefficients having $ \sqrt{1+i} $ as a root must also have $ -\sqrt{1+i} $, $ \overline{\sqrt{1+i}} $, $ -\overline{\sqrt{1+i}} $, and if it's degree 4, but the problem asks for quadratic. Unless $ \sqrt{1+i} $ is such that its minimal polynomial is quadratic, but it's not, as $ [\mathbb{Q}(\sqrt{1+i}):\mathbb{Q}] = 4 $. But perhaps in the context, they want $ (z - \sqrt{1+i})(z - \sqrt{1-i}) $, but again not real. After reconsideration, the intended solution likely assumes that the conjugate is included, and the polynomial is $ z^2 - 2\cos(\pi/8)\sqrt{2} z + \sqrt{2} $, but that's not nice. Alternatively, recognize that $ 1+i = \sqrt{2} e^{i\pi/4} $, so $ \sqrt{1+i} 📰 Spider-Man PNG – You NEED THIS jaw-dropping Hero Image for Your Social Media! 📰 Words On Sh 7965179 📰 Virtualbox Download For Mac 9292781 📰 Now In Sp 247707 📰 Motherload Miniclip The Wild Secret Behind Endless Hours Of Gaming Bliss 5768630 📰 Watch This Scorpio Man Transform Your Relationship Overnight Find Out How 3004332 📰 How Many Countries In The World Is There 5504835 📰 This Hidden Pop Up Christmas Tree Held A Secret That Shook The Whole Family 605758 📰 Ty Doran Movies And Tv Shows 8914316 📰 Vice Principals 2654786 📰 Cineby Just Unleashed The Ultimate Movie Experiencewatch The Clips That Are Blowing Up Online 6268677 📰 Al Unser Jr 1132649 📰 Rstrnt 1281169 📰 Zanies Nightclub 701103 📰 A High School Student Saves Money For College She Saves 250 In January 300 In February Then Increases Her Savings By 20 Each Month Thereafter How Much Does She Save In Total Over The First 6 Months 3145809 📰 Purchase Foreign Currency Bank Of America 9639573Final Thoughts
