These lead to the definitions or formulas for factoring perfect square trinomials and can also extend to factoring the difference of squares and the sum and difference of cubes. We have: x2 – y2 = (x – y)(x + y) and x3 – y3 = (x – y)(x2 + xy + y2) and x3 + y3 = (x – y)(x2 ( xy + y2)

Factoring Perfect Square Trinomials: Notice the form that a perfect square trinomial takes on. Factoring The Sum or Difference of Two Cubes: We also have nice formulas for the sum and difference of two cubes: To do this, it is necessary that you can notice perfect cubes quickly: EXAMPLE: List the perfect cubes of 1 through 7: Factor
Pre-Calculus
Have the students use the Bellringer to develop the steps for factoring a polynomial completely: (1) factor out GCF, (2) if the polynomial is a binomial, look for special products such as difference of two perfect squares or the sum/difference of two perfect cubes, and (3) if the polynomial is a trinomial, look for a perfect square trinomial or ...
Factoring Perfect Cubes - MathFlight Learning Resources
If factoring two terms that are perfect cubes, we can apply the sum or difference of cubes rule to help us factor. 1) Make two sets of parenthesis and put the cube root of each term in the first one and keep the sign. 2) Now work just with the first parenthesis to fill …
