Factoring Expressions (Difference of Two 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 x4 − yas (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 with polynomials.
