**Dividing Polynomials**

We will be examining polynomials divided by monomials and by binomials.

**Steps for Dividing a Polynomial by a Monomial:**

- Divide each term of the polynomial by the monomial.

a) Divide numbers (coefficients)

b) Subtract exponents

* The number of terms in the polynomial equals the number of terms in the answer when dividing by a monomial. - Remember that numbers do not cancel and disappear! A number divided by itself is
**1.**It reduces to the number 1. - Remember to write the appropriate sign in between the terms.

**Example:**

The polynomial on the top has 3 terms and the answer has 3 terms.

**Think about it:**

**Steps for Dividing a Polynomial by a Binomial:**

- Remember that the terms in a binomial cannot be separated from one another when reducing. For example, in the binomial 2x + 3, the 2x can never be reduced unless the entire expression 2x + 3 is reduced.
- Factor completely both the numerator and denominator before reducing.
- Divide both the numerator and denominator by their greatest common factor.

**Example 1:**

Notice that the x+1 was reduced as a “set”.

**Example 2:**

**Example 3:**

**Example 4:**

Tricky strategy: Notice that the -1 was factored out of the numerator to create a binomial compatible with the one in the denominator.

2 – x = -1(x – 2)
