Find the Factors: Step Title: Find the FactorsConcise Step Description: Find two numbers that multiply to the product of the first and last coefficients 3×−6=−18 and add to the middle coefficient 7.Step Calculation: Factors of −18 that add up to 7 are 9 and −2 (because 9×−2=−18 and 9+(−2)=7).Step Output: Factors: 9, −2
Write the Factored Form: Step Title: Write the Factored FormConcise Step Description: Write the factored form of the quadratic equation using the factors found in the previous step, and split the middle term accordingly.Step Calculation: The quadratic equation can be rewritten as 3x2+9x−2x−6. Now, group the terms to factor by grouping: (3x2+9x)+(−2x−6).Step Output: Grouped terms: (3x2+9x) and (−2x−6)
Factor by Grouping: Step Title: Factor by GroupingConcise Step Description: Factor out the greatest common factor from each group.Step Calculation: From the first group 3x2+9x, factor out 3x to get 3x(x+3). From the second group −2x−6, factor out −2 to get −2(x+3).Step Output: Factored groups: 3x(x+3) and −2(x+3)
Combine the Groups: Step Title: Combine the GroupsConcise Step Description: Combine the factored groups to write the final factored form of the quadratic equation.Step Calculation: Since both groups contain the factor (x+3), combine them to get (3x−2)(x+3).Step Output: Final factored form: (3x−2)(x+3)
