(x3 + 3x2 - 2x + 7)/(x + 1) = x2 + 2x - 4 + 11/(x + 1)
(multiply x + 1 by x2, and subtract the product from the dividend)
1. x2(x + 1) = x3 + x2
2. (x3 + 3x2 - 2x + 7) - (x3 + x2) = x3 + 3x2 - 2x + 7 - x3 - x2 = 2x2 - 2x + 7
(multiply x + 1 by 2x, and subtract the product from 2x2 - 2x + 7)
1. 2x(x + 1) = 2x2 + 2x
2. (2x2 - 2x + 7) - (2x2 + 2x) = 2x2 - 2x + 7 - 2x2 - 2x = -4x + 7
(multiply x + 1 by -4, and subtract the product from -4x + 7)
1. -4(x + 1) = -4x - 4
2. -4x + 7 - (-4x - 4) = -4x + 7 + 4x + 4 = 11(remainder)
