How to classify a polynomial by expanding

The video tutorial addresses common mistakes students make when squaring binomials, emphasizing that squaring a binomial is not the same as distributing the square across terms. It explains the correct method using the distributive property or foiling technique. The tutorial further discusses the importance of foiling to avoid errors and demonstrates the multiplication of expressions by multiplying each term. Finally, it classifies the resulting polynomial by its degree and number of terms, identifying it as a cubic trinomial.
