Q. Factor as the product of two binomials.\newlinex2x42=x^{2}-x-42=
  1. Identify Quadratic Expression: Identify the quadratic expression to be factored.\newlineThe given quadratic expression is x2x42x^2 - x - 42.
  2. Determine Factors: Determine the factors of the constant term that add up to the coefficient of the xx term.\newlineThe constant term is 42-42, and the coefficient of the xx term is 1-1. We need to find two numbers that multiply to 42-42 and add up to 1-1.
  3. List Factor Pairs: List the pairs of factors of 42-42. The pairs of factors of 42-42 are (1,42)(1, -42), (1,42)(-1, 42), (2,21)(2, -21), (2,21)(-2, 21), (3,14)(3, -14), (3,14)(-3, 14), (6,7)(6, -7), (6,7)(-6, 7).
  4. Find Correct Pair: Find the correct pair of factors that add up to 1-1. By checking the pairs, we find that 66 and 7-7 add up to 1-1.
  5. Write as Binomials: Write the quadratic expression as the product of two binomials using the found factors.\newlineThe quadratic expression x2x42x^2 - x - 42 can be factored as (x7)(x+6)(x - 7)(x + 6).
