Question

- [ 3a^2+2a^2+9a^2 - {6a^2-(-2a^2+3a^2)}] Simplify it

Answer 1

Like terms are terms that have the same variable part i.e. they only differ in their coefficients. Combining like terms is very often required in the process of simplifying equations.

For example:

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
