Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
Solve:
(x-5)(3x+4) = 0 Here, you would use the "zero product principle" which means: If a*b = 0, then either a = 0 or b = 0 or both.
Applying this principle to your particular problem, you get:
x-5 = 0 and/or 3x+4 = 0
If x-5 = 0, then x = 5
If 3x+4 = 0, then 3x = -4 and x = -4/3
