Proving the Polynomial Identity

This video tutorial teaches how to prove the polynomial identity (A+B)^2 = A^2 + 2AB + B^2 using algebraic models. It covers techniques for manipulating expressions without changing their value, addresses common misunderstandings in squaring sums, and provides a step-by-step algebraic proof of the identity. The tutorial concludes with a more complex example to reinforce the concepts.
