How can I anwser this ?? help me

Exactly like the previous question you posted.
-3x² - 9x = 0
Divide each side of the equation by -3 :
x² + 3x = 0
Factor the left side:
x (x + 3) = 0
This is true if x=0 or if x=-3 .

− 3 x 2 − 9 x = 0 − 3 x ( x + 3 ) = 0 x = 0 ∨ x = − 3

To solve − 3 x 2 − 9 x = 0 , first divide by -3 to get x 2 + 3 x = 0 . Then factor to find x ( x + 3 ) = 0 , giving solutions of x = 0 and x = − 3 .
