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 −7, −25, and −12.Step Calculation: Coefficients are −7, −25, −12Step Output: Coefficients: −7, −25, −12
Find Factors: Step Title: Find the FactorsConcise Step Description: Find two numbers that multiply to the product of the first and last coefficients (−7×−12=84) and add to the middle coefficient (−25).Step Calculation: Factors of 84 that add up to −25 are −4 and −21.Step Output: Factors: −4, −21
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: −7v2−4v−21v−12Step Output: Rewritten quadratic: −7v2−4v−21v−12
Factor by Grouping: Step Title: Factor by GroupingConcise Step Description: Group the terms into two pairs and factor out the greatest common factor from each pair.Step Calculation: Group 1: −7v2−4v, Group 2: −21v−12. Factor out −v from the first group and −3 from the second group.Step Output: Factored Groups: −v(7v+4)−3(7v+4)
Factor Out Common Binomial: Step Title: Factor Out the Common BinomialConcise Step Description: Factor out the common binomial (7v+4) from the two groups.Step Calculation: (7v+4)(−v−3)Step Output: Factored Form: (7v+4)(−v−3)
