Question

encontre as raises das equacoes do 2 grau x2+5x-24=0

Answer 1

$x^{2} +5x-24=0$

Δ = $5^{2} - 4(-24)$

Δ = $5^{2} +96$

Δ = $25+96$

Δ = $121$

$x_{1,2} = \frac{(-5)\± \sqrt{121} }{2}$

$x_{1,2} = \frac{(-5)\±11}{2}$

$x' = \frac{(-5)+11}{2}$

$x' = \frac{6}{2}$

$x' = 3$

$x'' = \frac{-5-11}{2}$

$x'' = \frac{-16}{2}$

$x'' = -8$

Answer 2

x2+5x-24=0
x2-5x-24=0
(x+30).(x-8=0)
X=-3,8
