Question

- 6x elevado a 2 - 16x = 0.

Answer 1

-6x^2 - 16x = 0

Usaremos o fator comum em evidência:
2x(-3x -8) = 0
• 2x = 0
• -3x -8
-3x = 8
3x = -8
x = -8/3

Answer 2

Oie, Td Bom?!

$- 6x {}^{2} - 16x = 0 \\ - 2x \: . \: (3x + 8) = 0 \\ x \: . \: (3x + 8) = 0$

$x = 0 \\ 3x + 8 = 0⟶x = - \frac{8}{3}$

S = $\left \{ x_{1} = - \frac{8}{3} \: , \: x_{2} = 0 \right \}$
