How to add polynomials

Sagot :

To add polynomials, combine the like terms, then follow the rules on adding integers.

Like terms are terms with same literal coefficients.

Literal coefficient is variable or variables and its exponent.

Example:

4x³ - 4xy² + xy² - 2x³

4x³ - 2x³ - 4xy² + xy²

Combine 4x³ and -2x³ = 2x³
Combine -4xy² and xy² = -3xy²

The result is:

2x³ - 3xy²
