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 5, −42, and 49.Step Calculation: Coefficients are 5, −42, 49Step Output: Coefficients: 5, −42, 49
Find Factors: Step Title: Find the FactorsConcise Step Description: Find two numbers that multiply to the product of the first and last coefficients 5×49=245 and add to the middle coefficient −42.Step Calculation: Factors of 245 that add up to −42 are −7 and −35.Step Output: Factors: −7, −35
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: Rewrite −42x as −7x−35x.Step Output: Rewritten quadratic: 5x2−7x−35x+49
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 −7 from the second pair.Step Output: Factored by grouping: x(5x−7)−7(5x−7)
Factor Out Common Binomial: Step Title: Factor Out the Common BinomialConcise Step Description: Factor out the common binomial factor from the two groups.Step Calculation: Factor out (5x−7).Step Output: Factored completely: (x−7)(5x−7)
