Question

Resolve a funçao g(x)= -2x²+3x+2​

Answer 1

Explicação passo-a-passo:

∆=3²-4.(-2).3

∆=9+16

∆=25

x=(-3±5)/-4

x'=2, x"=-1/2

Answer 2

Vamos achar as raízes

-2x²+3x+2=0

∆=3²-4.(-2).2

∆=9+16=25

x=(-b±√∆)/2a

$x =\frac{ - 3±5}{ - 4} \ \\ x' = \frac{ - 3 + 5}{ - 4} = \frac{2}{ - 4} = - \frac{1}{2} \\ x'' = \frac{ - 3 - 5}{ - 4} = \frac{ - 8}{ - 4} = 2$
