Q. Factor completely.\newline2x29x5 2 x^{2}-9 x-5 \newlineAnswer:
  1. Identify Coefficients: Identify the coefficients of the quadratic expression.\newlineThe quadratic expression is 2x29x52x^2 - 9x - 5. Here, a=2a = 2 (coefficient of x2x^2), b=9b = -9 (coefficient of xx), and c=5c = -5 (constant term).
  2. Find Multiplying Numbers: Determine two numbers that multiply to acac (aa times cc) and add up to bb. We need to find two numbers that multiply to (2)(5)=10(2)(-5) = -10 and add up to 9-9.
  3. Determine Numbers: Find the two numbers that meet the criteria.\newlineThe numbers 10-10 and 11 multiply to 10-10 and add up to 9-9. So, we can write 9x-9x as 10x+x-10x + x.
  4. Rewrite Expression: Rewrite the quadratic expression using the two numbers found.\newlineThe expression 2x29x52x^2 - 9x - 5 can be rewritten as 2x210x+x52x^2 - 10x + x - 5.
  5. Factor by Grouping: Factor by grouping.\newlineGroup the terms to factor by grouping: (2x210x)+(x5)(2x^2 - 10x) + (x - 5).
  6. Factor Common Factors: Factor out the common factors from each group.\newlineFrom the first group, 2x210x2x^2 - 10x, we can factor out 2x2x to get 2x(x5)2x(x - 5). From the second group, x5x - 5, we can factor out 11 to get 1(x5)1(x - 5).
  7. Write Factored Form: Write the factored form by combining the common factors.\newlineSince both groups contain the factor (x5)(x - 5), we can combine them to get the factored form: 2x(x5)+1(x5)2x(x - 5) + 1(x - 5).
  8. Combine Common Factors: Combine the common factors to complete the factoring.\newlineThe final factored form is (2x+1)(x5)(2x + 1)(x - 5).
