(4 Terms) Factoring Polynomials by Grouping

JtepS

Example

step 1: Group the first two terms together and the last two terms together.

Step 2: Factor out the GCF for each binomial.

Step 3: The GCF from each binomial will become one factor and remaining binomial will be the other factor.

Step 4: Use FOIL to check your answer.

Practice! 1.

+ 15x2 - 2;c - 10

Factor each polynomial by grouping. Check your answer 2. 12x + 2xy + 3y

3. x^ + 2 x ^ - 5 x - 1 0

4. x'^ + 4x^ + 2x + 8

5. 6y2

6. x^y + 3 x 2 - 7 y 2 - 2 1 y

7. lOx^ - 25x2

8. 6xy - x - 3
