Reviews the Binomial Square of a Sum special product rule, which is useful for understanding polynomial identities. Includes short multiple-choice quiz. [4:11]

Polynomial identities can be used to explain or describe various things in math. For example, we can use identities to prove that the differences between consecutive square numbers (1,4,9) are consecutive odd numbers (1,3,5). [4:33]

Sal considers two cases of polynomial identities and their proofs. [7:38]

Polynomial identities are equations that are true for all possible values of the variable. This introduction video gives more examples of identities and discusses how we prove an equation is an identity. [4:56]
