Mastering Factoring Techniques

This lesson covers solving polynomials by factoring. It begins with setting equations to zero, finding the greatest common factor (GCF), and using the zero product property. Several examples illustrate different scenarios, including solving cubic polynomials, handling non-zero starts, and using methods like the x factor and factor by grouping. The lesson concludes with factoring using the difference of squares.

What is the first step in solving polynomials by factoring?

• List all possible factors

• Determine the degree of the polynomial

• Set the equation to zero
