Learn the ac method for factoring and solving a quadratic equation

The video tutorial explains the process of factoring quadratic equations by grouping. It begins with an introduction to the concept and proceeds to identify the factors of 45. The instructor explains how to handle positive and negative sums, and demonstrates rewriting the equation by grouping terms. Finally, the tutorial covers factoring out the greatest common factor (GCF) to solve the equation.

What is the first step in factoring by grouping?

• Identify the greatest common factor

• Rewrite the equation in standard form

• Solve for x

• Rewrite the middle term as two separate values

When identifying factors of a number, what should you do if a number is not divisible by a smaller number?

• Stop the process

• Move to the next number

• Divide by a larger number

• Use a calculator

Which pair of factors of -45 adds up to -12?

• -18 and 6

• -9 and 5

• -15 and 3

• -10 and 4

What is the purpose of factoring out the greatest common factor (GCF) in the grouping method?

• To simplify the equation

• To eliminate variables

• To find the roots of the equation

• To make the terms identical for further factoring

After factoring by grouping, what property is used to solve the equation?

• Distributive Property

• Associative Property

• Zero Product Property

• Commutative Property
