📚 Combining Like Terms

What Are Like Terms?

1
Like terms have the same variable AND the same exponent.
3x and 5x are like terms (both have x¹)
4x² and 7x are NOT like terms (different exponents)
2
Constants (plain numbers) are always like terms with each other.
6 and −3 are like terms
3
To combine like terms, add or subtract the coefficients. Keep the variable the same.
4x + 5x = 9x

Worked Examples

▷
Simplify: 4x + 5x − 3 − 3x
x-terms: 4x + 5x − 3x = 6x
constants: −3
Answer: 6x − 3
▷
Simplify: 5x² + 2x − 3x − 4x²
x²-terms: 5x² − 4x² = x²
x-terms: 2x − 3x = −x
Answer: x² − x

⚠ Watch Out!

!
x² and x are NOT like terms — different exponents.
!
3x and 3y are NOT like terms — different variables.
!
1x can be written as just x. −1x is −x.
