Factoring Expressions (Trial & Error)
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 x4 – y4 as (x2)2 – (y2)2, thus recognizing it as a difference of squares that can be factored as (x2 – y2)(x2 + y2).
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
