This form of polynomials can be often factorized into a product of two binomials. Sometimes, we need to find the common factor of the polynomial before factorizing. We will learn it all in this lesson.

Basic Concepts: Prime factorization, Multiplying binomial by binomial, Common factors of polynomials
