Q. Factor the quadratic expression completely.\newline3x220x7=3x^{2}-20x-7=
  1. Identify Coefficients: Step Title: Identify the Coefficients\newlineConcise Step Description: Identify the coefficients of the quadratic expression, which are the numbers in front of the variables. In this case, the coefficients are 33, 20-20, and 7-7.\newlineStep Calculation: Coefficients are 33, 20-20, 7-7\newlineStep Output: Coefficients: 33, 20-20, 7-7
  2. Find Factors: Step Title: Find the Factors\newlineConcise Step Description: Find two numbers that multiply to the product of the first coefficient 33 and the last term 7-7, which is 21-21, and add to the middle coefficient 20-20.\newlineStep Calculation: Factors of 21-21 that add up to 20-20 are 1-1 and 21-21.\newlineStep Output: Factors: 1-1, 21-21
  3. Rewrite Middle Term: Step Title: Rewrite the Middle Term\newlineConcise Step Description: Rewrite the middle term using the factors found in the previous step.\newlineStep Calculation: Rewrite 20x-20x as x21x-x - 21x.\newlineStep Output: Rewritten expression: 3x2x21x73x^2 - x - 21x - 7
  4. Group Terms: Step Title: Group the Terms\newlineConcise Step Description: Group the terms in pairs to factor by grouping.\newlineStep Calculation: Group (3x2x)(3x^2 - x) and (21x7)(-21x - 7).\newlineStep Output: Grouped expression: (3x2x)(21x+7)(3x^2 - x) - (21x + 7)
  5. Factor Each Group: Step Title: Factor Each Group\newlineConcise Step Description: Factor out the greatest common factor from each group.\newlineStep Calculation: Factor out xx from the first group and 7-7 from the second group.\newlineStep Output: Factored groups: x(3x1)7(3x1)x(3x - 1) - 7(3x - 1)
  6. Factor Out Common Binomial: Step Title: Factor Out the Common Binomial\newlineConcise Step Description: Factor out the common binomial factor from the two groups.\newlineStep Calculation: Factor out (3x1)(3x - 1).\newlineStep Output: Factored expression: (3x1)(x7)(3x - 1)(x - 7)
