2.ab,3ba
3.-5b,9b
4.ab,-3a
​

Answer 1

Answer:

2. ab, 3ba

3. -5b, 9b

Step-by-step explanation:

there are two correct answers.

Answer 2

Answer:

For examples:

2x and –5x are like terms.

a and 1/2 a are like terms.

6x and 5y are unlike terms.

Like terms can be added or subtracted from one another.

For example:

a + a = 2 × a = 2a (We usually write 2 × a as 2a)

2a + 4a = 6a

a + a + a = 3a

2a + 4 (Unlike terms cannot be simplified)

4a + 3b (Unlike terms cannot be simplified)

6a – 3a = 3a

8b – 8b = 0

5a – 3 (Unlike terms cannot be simplified)

6a – 4b (Unlike terms cannot be simplified)
