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
Rewrite Middle Term: Step Title: Rewrite the Middle TermConcise Step Description: Rewrite the middle term using the factors found in the previous step.Step Calculation: The quadratic equation can be rewritten as 2x2+7x−2x−7=0.Step Output: Rewritten Equation: 2x2+7x−2x−7=0
Factor by Grouping: Step Title: Factor by GroupingConcise Step Description: Group the terms into two pairs and factor out the common factors from each pair.Step Calculation: Factor out x from the first pair and −1 from the second pair to get x(2x+7)−1(2x+7)=0.Step Output: Factored by Grouping: x(2x+7)−1(2x+7)=0
Factor Out Binomial: Step Title: Factor Out the Common BinomialConcise Step Description: Factor out the common binomial factor from the two groups.Step Calculation: The common binomial factor is (2x+7), so the factored form is (x−1)(2x+7)=0.Step Output: Factored Form: (x−1)(2x+7)=0
