Two polynomials P and D are given. Use either synthetic or long division to divide P(x) by D(x),and express P in the form P(x) = D(x) · Q(x) + R(x).
a) P(x) = −x^3 − 5x + 3, D(x) = x + 1
b) P(x) = 27x^5 − 9x^4 + 3x^2 − 3, D(x) = 3x^2 − 3x + 1

( −x^3 − 5x + 3) / (x + 1)
( −x^3 − 5x + 3) / (x + 1)
−x^3 − 5x + 3, D(x) = x + 1
-1 0 -5...3
....1..-1..6
----------------
-1..1..-6..9
so that's (x+1)(-x^2+x-6) R 9
