2. Dividing Polynomials

3. Example
2X2+14x−16 X−1

4. Step 1: Factor the Numerator
What is a Numerator?
The Top Part of a Fraction

5. Step 1: Factor the Numerator
2X2+14x−16 X−1
Factor 2x2+14x-16
(2)(x+8)(x−1) X−1

6. Step 2: Cancel out Common Factors
(2)(x+8)(x−1) X−1

7. Step 3: Whatever is Left is your Answer
(2)(X+8)

8. Example 2
7g-1
(49g2-1)÷(7g+1)
49g2−1 7g+1
(7g−1)(7g+1) 7g+1

9. Example 3 (3x+2)(x−9) x−3 (3x+2) (3x2-7x-6)÷(x-3) 3x2− 7x−6 x−3

10. Simplify x2+2x−63 x+9
A.) x-7 B.) x2-7 C.) x+7 D.) x2+3x-54

11. Dividing Polynomials using a Table Match
The easy way

12. Step 1: Go to y=

13. Step 2: Type your equation into y1

14. Step 3: Type your First Answer Choice into y2

15. Step 4: Go to the Table

16. Step 5: Check that y1 and y2 match

17. Step 6: If it does not match, Type your next choice into y2 until it does match
