# Factoring Expressions (Perfect Squares)

Videos and lessons to help High School students learn to use the structure of an expression to identify ways to rewrite it. *For example, see x*^{4} – y^{4 }as (x^{2})^{2} – (y^{2})^{2}, thus recognizing it as a difference of squares that can be factored as (x^{2} – y^{2})(x^{2} + y^{2}).

### Suggested Learning Targets

- Use factoring techniques such as common factors, grouping, the difference of two squares, the sum or
difference of two cubes, or a combination of methods to factor completely.
- Simplify expressions including combining like terms, using the distributive property and other operations
with polynomials.
