(x3 + 4x2 - 3x - 12)/(x2 - 3) = x + 4

(multiply x2 - 3 by x, and subtract the product from the dividend)

1. x(x2 - 3) = x3 - 3x = x3 + 0x2 - 3x

2. (x3 + 4x2 - 3x - 12) - (x3 + 0x2 - 3x) = x3 + 4x2 - 3x - 12 - x3 + 3x = 4x2 - 12

(multiply x2 - 3 by 4, and subtract the product from 4x2 - 12)

1. 4x(x - 3) = 4x2 - 12 = 4x2 - 12

2. (4x2 - 12) - (4x2 - 12) = 4x2 - 12 - 4x2 + 12 = 0(remainder)
