Question

$8x {}^{2} + 6x = 0$
​

Answer 1

8x² + 6x=0

  x(8x + 6) = 0

  x = 0

 8x² + 6x = x.(8x+6)= - 6; x= -3/4

 s = { 0, 3/4 }

Answer 2

Resposta:

x' = 0

X" = - 3/4

Explicação passo-a-passo:

8x^2 + 6x = 0

X.(8x+ 6)= 0

X = 0

8x + 6 = 0

8x = - 6 (:2)

4x = - 3

X = - 3/4

R.:

x' = 0

X" = - 3/4
