(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)

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!!!!
Divide all terms by 4:- x2+7x+12 = (x+3)(x+4) when factored
x3 + 3x2 - 4x -12 x2(x + 3) - 4(x + 3) (x2 - 4)(x+3)
Divide both sides of the equation by x: x2 = 9x x2 / x = 9x / x x = 9
x²-x-12=0 x1=-(-1/2) - Square root of ((-1/2)²+12) x1=0.5 - 3.5 x1=-3 x2=-(-1/2) + Square root of ((-1/2)²+12) x2=0.5 + 3.5 x2=4
If you mean: x squared -7x +12 then it is (x-3)(x-4) when factored
