How to factor difference of squares & perfect square trinomials | Math Hacks

Brett introduces the formulas used for factoring difference of perfect squares and perfect square trinomials beginning with a simple example and working our way up to more difficult factoring with repeated use of the difference of squares formula. Problems include factoring: x^8 - 1, and 4x^2 - 12x + 9. For new math tutorials every week, click here: https://www.youtube.com/c/mathhacks?s... This lesson is part of the FACTORING POLYNOMIALS series which includes factoring techniques such as standard factoring, factoring out the GCF, the ACB method for factoring quadratics with leading coefficients greater than 1, polynomial long division and synthetic division. » FACTORING POLYNOMIALS PLAYLIST:    • Factoring Polynomials 📓   For more algebra 1 help: » CRUSH YOUR ALGEBRA GOALS PLAYLIST:    • Crush your Algebra Goals 🏆   PREVIOUS LESSON: Factor by Grouping »    • FACTOR BY GROUPING » how to factor polynom...   SKIP AHEAD Intro to Difference of Perfect Squares formula » 0:58 Factoring the difference of perfect squares (x^2 - 9) » 1:53 How to check your solution » 3:05 Factoring difference of perfect squares w/ leading coefficient (4x^2 - 25) » 4:07 Factoring a repeated difference of squares problem (x^8 - 1) » 5:07 Intro to Perfect Square Trinomial formulas » 8:14 Factoring a perfect square trinomial (all positives terms) » 8:32 Factoring a perfect square trinomial (negative middle term) » 10:49 STAY CONNECTED » Instagram:   / mathhacksco   » Facebook:   / mathhacksco   » Blog:   / i   » Twitter:   / mathhacksco
