Identify Coefficients: Step Title: Identify the CoefficientsConcise Step Description: Identify the coefficients of the quadratic equation, which are the numbers in front of the variables. In this case, the coefficients are 2, 5, and −7.Step Calculation: Coefficients are 2, 5, −7Step Output: Coefficients: 2, 5, −7
Find Factors: Step Title: Find the FactorsConcise Step Description: Find two numbers that multiply to the product of the leading coefficient 2 and the constant term −7, which is −14, and add to the middle coefficient 5.Step Calculation: Factors of −14 that add up to 5 are 7 and −2.Step Output: Factors: 7, −2
Write 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 apply the AC method for factoring.Step Calculation: Rewrite the middle term using the factors 7 and −2: 2x2+7x−2x−7. Group the terms: (2x2+7x)−(2x+7). Factor by grouping: x(2x+7)−1(2x+7). Factor out the common binomial: (2x+7)(x−1).Step Output: Factored Form: (2x+7)(x−1)
