The video tutorial explains solving equations by replacing variables and applying the zero product property. It discusses the concept of multiplicity and its impact on graph behavior, such as crossing or bouncing at zeros. The tutorial also covers sketching polynomial graphs by hand, focusing on end behavior and graphing techniques without technology.

What is the first step in solving a polynomial equation?

• Set the equation to zero

• Factor the polynomial

• Graph the polynomial

• Find the degree of the polynomial
