3x^2 - 6x = 0
factors into:
(3x)(x - 2) = 0
so 3x = 0, and x - 2 = 0
3x = 0
3x/3 = 0/3
x = 0
(x - 2) = 0
x = 2
x = 0, 2
check by plugging answers back into equation:
if x = 0
3x^2 - 6x = 0
3(0) - 6(0) = 0
0 - 0 = 0
0 = 0
if x = 2
3x^2 - 6x = 0
3(2)^2 - 6(2) = 0
3(4) - 12 = 0
12 - 12 = 0
0 = 0

3x^2 - 6x = 0 or x^2 - 2x = 0
x (x - 2) = 0 and so x = 0 and x = 2 are the two possible solutions.

Take 3x common frm above equ.
3x(x-2)=0
3x=0 & x-2=0
x=0 & 2

Factor out an "x".
x [3x-6]=0
You have two solutions then.
1st solution:
x=0
2nd solution
3x-6=0
3x=6
Divide by 3 each side
x=2
