• As the sum of two terms with coefficients -6 and 10

• Using the quadratic formula

What is the purpose of breaking up the middle term in the process of factoring by grouping?

• To create groups for factoring

• To simplify the expression

• To identify the common factors

• To apply the quadratic formula

What common factor is factored out from the first group during the grouping process?

• -3
