Q. Factor the quadratic expression completely.−3x2+17x−20=
Identify Coefficients: Step Title: Identify the CoefficientsConcise Step Description: Identify the coefficients of the quadratic expression, which are the numbers in front of the variables. In this case, the coefficients are −3, 17, and −20.Step Calculation: Coefficients are −3, 17, −20Step Output: Coefficients: −3, 17, −20
Find Factors: Step Title: Find the FactorsConcise Step Description: Find two numbers that multiply to the product of the first and last coefficients (−3×−20=60) and add to the middle coefficient (17).Step Calculation: Factors of 60 that add up to 17 are 5 and 12.Step Output: Factors: 5, 12
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: −3x2+12x+5x−20Step Output: Rewritten Expression: −3x2+12x+5x−20
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: Group 1: −3x2+12x, Group 2: 5x−20. Factor out the common factors: −3x(x−4)+5(x−4).Step Output: Factored Groups: −3x(x−4)+5(x−4)
Factor Out Common Binomial: Step Title: Factor Out the Common BinomialConcise Step Description: Factor out the common binomial (x−4) from the expression.Step Calculation: (x−4)(−3x+5)Step Output: Factored Expression: (x−4)(−3x+5)
