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) = x⁴ + 2x³ 16x, D(x) = x 4

P(x)= ____?

B.

P(x) = 4x³ + 5x + 9, D(x) = 2x + 1

P(x)= ____?

C.

P(x) = 20x⁴ + 16x³ + 9x², D(x) = 4x² + 1

P(x)= ____?
