Problem
(x + 2)(3x - 4)(3x) = 0
Solve for x.
Solution
For this case since we have a mutliplication of terms equal to 0 we can do the following:
x+2 =0
x= -2
3x -4=0
We add 4 in both sides and we got:
3x -4+4 =0+4
3x=4
Then we divide both sides by 3 and we got:
3x/3 = 4/3
x= 4/3
3x=0
x=0
And then we have 3 solutions:
x= -2 , x = 4/4 , x= 0
