How do i divide x2 - x - 12 by x - 4?
x2 - x - 12First try and factor that expression.Notice that it happens to be the product of (x - 4) and (x + 3). This makes your problem easy.(x2 - x - 12) / (x - 4)= (x - 4) (x + 3) / (x - 4)Now just divide numerator and denominator by the common factor. ("Cancel" (x - 4) out of numerator and denominator.)Wind up with the answer = (x + 3)
