x^2 -x -12 / (x - 4)
Factor ise the top line
(x + 3)(x - 4) / (x - 4)
Cancel down by 'x-4'
Hence
x + 3 is the answer!!!!

∙ 11y ago(x^2 - x - 12) = (x^2 - 4x + 3x -12) = x(x -4) + 3(x -4) = (x-3) x (x-4)
Hence (x^2 - x - 12) divided by (x -4) is (x-3)

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)
