2x^3+16x^2+32x=0
Please show step by step.
It seems I'm able to get part of the answer (-4) but not the other part (0)
This is how I did it, I factored it first:
2x(x^2+8x+16)=0, then factored it again
(x+4) (x+4) but this is wrong because then I did
x+4=0 | x+4=0
(I minus -4 on both sides of the = sign for the left equation and the right equation; and get (-4) for both of them, but the correct answer is (0) & (-4)
Please help. Thanks.
