Q. Factor completely.\newline5x242x+49 5 x^{2}-42 x+49 \newlineAnswer:
  1. Identify Coefficients: Step Title: Identify the Coefficients\newlineConcise Step Description: Identify the coefficients of the quadratic equation, which are the numbers in front of the variables. In this case, the coefficients are 55, 42-42, and 4949.\newlineStep Calculation: Coefficients are 55, 42-42, 4949\newlineStep Output: Coefficients: 55, 42-42, 4949
  2. Find Factors: Step Title: Find the Factors\newlineConcise Step Description: Find two numbers that multiply to the product of the first and last coefficients 5×49=2455 \times 49 = 245 and add to the middle coefficient 42-42.\newlineStep Calculation: Factors of 245245 that add up to 42-42 are 7-7 and 35-35.\newlineStep Output: Factors: 7-7, 35-35
  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 42x-42x as 7x35x-7x - 35x.\newlineStep Output: Rewritten quadratic: 5x27x35x+495x^2 - 7x - 35x + 49
  4. Factor by Grouping: Step Title: Factor by Grouping\newlineConcise Step Description: Group the terms into two pairs and factor out the common factors from each pair.\newlineStep Calculation: Factor out xx from the first pair and 7-7 from the second pair.\newlineStep Output: Factored by grouping: x(5x7)7(5x7)x(5x - 7) - 7(5x - 7)
  5. 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 (5x7)(5x - 7).\newlineStep Output: Factored completely: (x7)(5x7)(x - 7)(5x - 7)
