Using synthetic division:
x^3 + 4x^2  3x  12 / x^2  3
Write it out like a long division problem. x^3 goes into x^3 + 4x^2 3x 12x times. This is the first term of the answer. Multiply x by x^2 3 and write the product under the dividend. That would be x^3 3x. Subtract x^3  3x from the dividend and you have 4x^2 12 left over. How many times does x3 go into that? Add that to the x in the quotient.
The answer is x+4
