1. Warm-up 6-4

2. Lesson 6-4: Division of Polynomials
Objective:
Students will divide polynomials

3. Dividing by a monomial
Separate terms and factor each

4. eliminate the 1st term of
Dividing by a polynomial
Set up in long division
2 terms in divisor (x + 1).
How does this go into 1st
two terms in order to
eliminate the 1st term of
the dividend. 2x
+ 1
Multiply by the divisor
Write product under dividend
Subtract
Carry down next term
Repeat process -
2x2 + 2x -
x + 5 -
x + 1 - 4
Answer:

5. HW 67 HINTS: If a term is missing in the dividend – add a “0” term.
If there is a remainder, put it over the divisor and add it to the quotient (answer)
Example 1
x4 – x2 + x ÷ x2 - x + 1
