Question

Solve by Factoring: 3x2 = -9x

What are the solutions for x?

x = 3, x = 9
x = 0, x = 3
x = 0, x = -3
none of the above

Answer 1

3x^2 = -9x
3x^2 + 9x = 0
3x(x-3) = 0

x = 0, 3

Answer 2

Isn't it -3 and 0?

Answer 3

3x^2= -9x --- 3x^2+9x=0
3x(x+3) = 0
3x= 0 and x+3=0
x=0 x= -3

x= (0, -3)

Answer 4

yeah, it's what happens when you write too fast.

Answer 5

Haha

Answer 6

x = 0,-3
