Factoring with Greatest Common Factor and Solving Quadratic Equations

This video tutorial covers factoring quadratic equations using the greatest common factor (GCF) and cases where the leading coefficient is one. It explains how to identify and factor out the GCF, determine two numbers that multiply to the constant term and add to the linear coefficient, and solve the resulting equations. The tutorial includes examples with both positive and negative constant terms, demonstrating the process step-by-step.

What is the first step in factoring a quadratic equation with a greatest common factor?

• Set the equation to zero

• Find two numbers that add to B

• Multiply the terms

• Factor out the greatest common factor
