Polynomials I

Posted by ricardogm on October 26th, 2017

We are going to practice a lot. Really. Solve the exercises in your notebook and use Symbolab to correct them.

1. Given the polynomials:

P(x) = x4 − 2x2 − 6x − 1

Q(x) = x3 − 6x2 + 4

R(x) = 2x4 − 2x − 2

Calculate:

  • P(x) + Q(x) − R(x) =
  • P(x) + 2 Q(x) − R(x) =
  • Q(x) + R(x) − P(x)=
  • P(x)·Q(x)=
  • Q(x)·R(x)=

2. Multiply:

  • (x4 − 2x2 + 2) · (x2 − 2x + 3) =
  • (3x2 − 5x) · (2x3 + 4x2 − x + 2) =
  • (2x2 − 5x + 6) · (3x4 − 5x3 − 6x2 + 4x − 3) =

3. Divide:

  • (x4 − 2x3 − 11x2 + 30x − 20) : (x2 + 3x − 2)
  • (x 6 + 5x4 + 3x2 − 2x) : (x2 − x + 3)
  • P(x) = x5 + 2x3 − x − 8 : Q(x) = x2 − 2x + 1
