Q. Factor as the product of two binomials.\newlinex29x+20=x^{2}-9x+20=
  1. Identify quadratic trinomial: Identify the quadratic trinomial and its structure.\newlineThe given expression is x29x+20x^2 - 9x + 20, which is in the standard form of a quadratic trinomial ax2+bx+cax^2 + bx + c, where a=1a = 1, b=9b = -9, and c=20c = 20.
  2. Determine factors of constant term: Determine the factors of the constant term cc that add up to the coefficient bb.\newlineWe need to find two numbers that multiply to 2020 (the constant term) and add up to 9-9 (the coefficient of xx). The numbers that satisfy these conditions are 4-4 and 5-5, because (4)×(5)=20(-4) \times (-5) = 20 and (4)+(5)=9(-4) + (-5) = -9.
  3. Rewrite middle term: Rewrite the middle term using the numbers found in Step 22.\newlineWe can express 9x-9x as the sum of 4x-4x and 5x-5x. Therefore, x29x+20x^2 - 9x + 20 can be rewritten as x24x5x+20x^2 - 4x - 5x + 20.
  4. Factor by grouping: Factor by grouping.\newlineWe group the terms as follows: (x24x)+(5x+20)(x^2 - 4x) + (-5x + 20). Now we factor out the common factors from each group. From the first group, we can factor out an xx, and from the second group, we can factor out a 5-5.\newlineThis gives us x(x4)5(x4)x(x - 4) - 5(x - 4).
  5. Factor out common binomial factor: Factor out the common binomial factor.\newlineWe notice that (x4)(x - 4) is a common factor in both terms. We can factor this out to get (x4)(x5)(x - 4)(x - 5) as the final factored form of the expression.
