Factoring and Solving Equations

The video tutorial explains how to solve equations by factoring, focusing on identifying and factoring out the greatest common factor. Two examples are provided: solving X^2 + 4X = 0 and 14X^2 - 35X = 0. The zero product property is used to find solutions, emphasizing the importance of factoring out the greatest common factor as the first step. The tutorial concludes with a reminder of this key point.

What is the first step in solving an equation by factoring?

• Using the zero product property

• Factoring out the greatest common factor

• Solving for x

• Adding terms on both sides
