In this lesson, students learn how to factor difference of square polynomials using algebra tiles and the formula a² - b² = (a + b)(a - b). The lesson also includes practice problems for factoring trinomials and perfect squares. Additionally, the instructor shares a mental math trick for multiplying large numbers using the difference of squares formula. Recognizing the difference of squares can simplify factoring and make the process much quicker.
Factoring difference of square polynomials, including a way to multiply large numbers with mental math. Also, more factoring trinomial practice.
