Dividing Polynomials

Example 2X2+14x−16 X−1

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

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

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

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

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

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

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