How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of the terms that have the same variable. For example, 3x + 5x = (3+5)x = 8x.

Front

Simplify: -x² + 7x - 10 + 4x² - 6x + 8

Back

3x² + x - 2.

Front

Simplify: 4x² - 3x + 11 - 2x

Back

4x² - 5x + 11.

Front

Simplify: n + 10 + 9n - 3

Back

10n + 7.

Front

Simplify: 5a + 2b - 3a + 4

Back

2a + 2b + 4.

Front

Simplify: 3x² - x + 2 - 5x² + 8x - 5

Back

-2x² + 7x - 3.
