Division of Polynomials

We’ve learned how to solve quadratics (which is a type of polynomials) by:

• Factoring • Completing the square•Quadratic formula.

Review

How do we find the zeros for:

Or a higher degree polynomial?

Introduction

For polynomials (including quadratics) we can find roots by dividing polynomials. There are two methods that will be introduced:

1)Long division2)Synthetic division

Intro. Cont.

As you watch the videos, think of these questions:

1) What is really a factor?2) What does it mean when we have a remainder

of 0?3) What about when it is not 0?

NOTES

Make a T-chart with Long division on one side and Synthetic Division on the other side.

1. Solve an example from the video using both methods2. Compare the two.
