Objective: students will be able to combine like terms to form a more compact equation

2. What Terms Can I Combine
Terms must have the same: VARIBALE (letter) EXPONENT

3. Like Terms Unlike Terms
examples
Like Terms 5x 4x
𝑥 2
4𝑥 2
5.8 6
Unlike Terms
5𝑥 2 5y x

4. Example 1
3x + 2y + 4x - y

5. Examples
16x – 7y + 3x – 8y
5a2 – 6a + 7a2 + 3a – 2 + 8a + 7
2h2 – 7h + 2h2 – h h – 9h

6. Distribute
5(a + b) +6a + 3a + 5
8(r – 2) + 4r – r + 14

7. 7 (x – y) + 8y – 3x – 2x + 15w 3 (w + v) – 12v + 7 w + 3w
practice
7 (x – y) + 8y – 3x – 2x + 15w
3 (w + v) – 12v + 7 w + 3w
12(a + b) + 3ab – 2a + 7b + 8ab
4h4j – 14h3j2 + 16h2j2 +13hj +15h3j2
