Question

resolva a equação de segundo grau determinando as raizes x1 e x2

a- x2-36=0

Answer 1

a=1

b=0

c=-36

$x = \frac{ - b + - \sqrt{ {b}^{2} - 4 \times a \times c} }{2 \times a} \\ x = \frac{0 + - \sqrt{ {0}^{2} - 4 \times 1 \times ( - 36) } }{2 \times 1} \\ x = \frac{0 + - \sqrt{144} }{2} \\ x = \frac{0 + - 12}{2} \\ x1 = \frac{0 - 12}{2} = \frac{ - 12}{2} = - 6 \\ x2 = \frac{0 + 12}{2} = \frac{12}{2} = 6$
