Q. Factor the quadratic expression completely.\newline8x218x5=8x^{2}-18x-5=
  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 88, 18-18, and 5-5.\newlineStep Calculation: Coefficients are 88, 18-18, 5-5\newlineStep Output: Coefficients: 88, 18-18, 5-5
  2. Find Product and Sum: Step Title: Find the Product and Sum\newlineConcise Step Description: Find two numbers that multiply to the product of the first and last coefficients 8×5=408 \times -5 = -40 and add to the middle coefficient 18-18.\newlineStep Calculation: We need to find two numbers that multiply to 40-40 and add to 18-18.\newlineStep Output: After testing different combinations, we find that 20-20 and +2+2 multiply to 40-40 and add to 18-18.
  3. Rewrite Middle Term: Step Title: Rewrite the Middle Term\newlineConcise Step Description: Rewrite the middle term of the quadratic expression using the two numbers found in the previous step.\newlineStep Calculation: Rewrite 18x-18x as 20x+2x-20x + 2x.\newlineStep Output: The expression becomes 8x220x+2x58x^2 - 20x + 2x - 5.
  4. Factor by Grouping: Step Title: Factor by Grouping\newlineConcise Step Description: Group the terms into two pairs and factor out the greatest common factor from each pair.\newlineStep Calculation: Factor out 4x4x from the first pair and 11 (or just factor the sign) from the second pair.\newlineStep Output: The expression becomes 4x(2x5)+1(2x5)4x(2x - 5) + 1(2x - 5).
  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: The common binomial factor is (2x5)(2x - 5).\newlineStep Output: The factored form is (2x5)(4x+1)(2x - 5)(4x + 1).
