Question

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).P(x) = 4x*2 + 5x − 1, D(x) = x + 3

Answer 1

-3 ) 4 5 -1

-12 21

4 -7 20. Bring down the 4. Multiply 3 times 4, place the answer under the 5

Add down to get -7. Multiply -3 times -7, place the answer under the -1. Add.

(4x² + 5x - 1)/(x + 3) = 4x - 7 + 20/(x+3)

Answer 2

Q(x) = 4x -7

R(x) = 20/(x+3)

If you don't get the above, ask for additional help.
