**Main idea** **- Solving Problems in the grouping method you have to group 2 polynomials and solve them both and put their answers together. When factoring a trinomial that cannot be factored you have to use the grouping method to solve the equation. **======

**Example #1** **.**
Example # 3.

**Factor by grouping: Practice Problem #1**
x 2 +4xy + 3x + 12y

Practice Problem 2
