# Multiplying Polynomials

How to solve multiplying polynomial problems: examples and their solutions. (binomials, trinomials)

## Example 1

Solve it like using the FOIL method.

Write the like terms vertically:

-*x*^{2}, -3*x*^{2}

+7*x*, +3*x*

Then add and subtract the like terms vertically.

## Example 2

Write the like terms vertically:

-*x*^{3}, +21*x*^{3}

+8*x*^{2}, -7*x*^{2}, -3*x*^{2}

+56*x*, +*x*

Then add and subtract the like terms vertically.
