Special Products. 1. Special Products involving Squares. The following special products come from multiplying out the brackets. You'll need these often, so it's worth knowing them well. a(x + y) = ax + ay (Distributive Law) (x + y) (x − y) = x 2 − y 2 (Difference of 2 squares) (x + y) 2 = x 2 + 2xy + y 2 (Square of a sum)
Special products are the result of binomials being multiplied, or simplified further, and can be solved with ease using the FOIL method: first, outer, inner, last. Learn how to use these steps,...
Recognize and Use the Appropriate Special Product Pattern. We just developed special product patterns for Binomial Squares and for the Product of Conjugates. The products look similar, so it is important to recognize when it is appropriate to use each of these patterns and to notice how they differ.
We have seen that some binomials and trinomials result from special products—squaring binomials and multiplying conjugates. If you learn to recognize these kinds of polynomials, you can use the special products patterns to factor them much more quickly.
In the previous chapter, we recognized two special products: Difference of two squares and Perfect square trinomials. In this section, we discuss these special products to factor expressions.

Sal gives numerous examples of the two special binomial product forms: perfect squares and the difference of two squares. Created by Sal Khan and CK-12 Foundation.
Google Classroom. A review of the difference of squares pattern (a+b) (a-b)=a^2-b^2, as well as other common patterns encountered while multiplying binomials, such as (a+b)^2=a^2+2ab+b^2. These types of binomial multiplication problems come up time and time again, so it's good to be familiar with some basic patterns.
