Q. Factor the quadratic expression completely.2x2−13x+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 2, −13, and 20.Step Calculation: Coefficients are 2, −13, 20Step Output: Coefficients: 2, −13, 20
Find Factors: Step Title: Find the FactorsConcise Step Description: Find two numbers that multiply to the product of the first and last coefficients 2×20=40 and add to the middle coefficient −13.Step Calculation: Factors of 40 that add up to −13 are −5 and −8.Step Output: Factors: −5, −8
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: 2x2−5x−8x+20Step Output: Rewritten Expression: 2x2−5x−8x+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: (2x2−5x)+(−8x+20)=x(2x−5)−4(2x−5)Step Output: Grouped Factors: x(2x−5)−4(2x−5)
Factor Out Common Binomial: Step Title: Factor Out the Common BinomialConcise Step Description: Factor out the common binomial factor from the grouped terms.Step Calculation: (x−4)(2x−5)Step Output: Factored Form: (x−4)(2x−5)
