Adding polynomials requires us to first identify then combine like terms.

Remember that like terms are terms with the exact same variable part.

**Add the polynomials**.

When subtracting polynomials you distribute the negative one first and then identify and combine like terms.

**Subtract the polynomials**.

We may encounter function notation,

In this case, just add or subtract the given polynomials as we did in the above examples.

**For the given functions find (***f* + *g*)(*x*) and (*f* - *g*)(*x*).
