In Example 10, change both − signs to + and then factor.

**Data from Example 10**

Factor: 2x − 2y + ax − ay.

We see that there is no common factor to all four terms, but that each of the first two terms contains a factor of 2, and each of the third and fourth terms contains a factor of a. Grouping terms this way and then factoring each group, we have

**Transcribed Image Text:**

## 2x - 2y + ax - ay = (2x - 2y) + (ax - ay) = 2(x - y) + a(x - y) = (x - y)(2 + a)
