# Introduction to special products of binomials | Algebra I | Khan Academy

Khan Academy presents Special Products of Binomials, an educational video resource on math.

# Factoring special products | Polynomial and rational functions | Algebra II | Khan Academy

This instructor in this video, Sal Khan, discusses how to factor special products. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The student or educator may want to open the video to 'full screen' as the instructor is using a black background and the writing is small.

# Factor polynomials with special product forms

Sal factors 25x^4-30x^2+9 as (5x^2-3)^2.

# Factor polynomials with special product forms

Sal factors 49x^2-49y^2 as (7x+7y)(7x-7y) or as 49(x+y)(x-y).
