Question

X elevado a 2 menos 16 x 46 = 0 ​

Answer 1

$x {}^{2} - 16 \times 46 = 0$

$x {}^{2} - 736 = 0 \\ a = 1 \\ b = 0 \\ c = - 736 \\ b² - 4 \times a \times c \\ 0 {}^{2} - 4 \times 1( - 736) \\ ∆ = 2944 < discriminante$

$x = \frac{ - 0± \sqrt{0 {}^{2 } - 4 \times 1( - 736)} }{2} \\ x = \frac{± \sqrt{0 + 2944} }{2} \\ x = \frac{± \sqrt{2944} }{2} \\ x = \frac{±8 \sqrt{46} }{2} \\ x = \frac{8 \sqrt{46} }{2} = 4 \sqrt{46} \\ x = \frac{ - 8 \sqrt{46} }{2} = -4 \sqrt{46} \\ S = - 4 \sqrt{46} \: \: \: , \: \: 4 \sqrt{46}$
