Q. Which of the following is equivalent to the expression x25x14 x^{2}-5 x-14 ?\newlineChoose 11 answer:\newline(A) (x14)(x+1) (x-14)(x+1) \newline(B) (x7)(x+2) (x-7)(x+2) \newline(C) (x2)(x+7) (x-2)(x+7) \newline(D) (x1)(x+14) (x-1)(x+14)
  1. Factor the quadratic expression: Factor the quadratic expression x25x14x^2 - 5x - 14.\newlineTo factor a quadratic expression of the form ax2+bx+cax^2 + bx + c, we need to find two numbers that multiply to acac (the product of the coefficient of x2x^2 and the constant term) and add up to bb (the coefficient of xx).\newlineHere, a=1a = 1, b=5b = -5, and c=14c = -14.\newlineWe need two numbers that multiply to (1)(14)=14(1)(-14) = -14 and add up to ax2+bx+cax^2 + bx + c00.
  2. Find two numbers: Find two numbers that multiply to 14-14 and add up to 5-5.\newlineThe numbers 7-7 and +2+2 multiply to 14-14 and add up to 5-5.\newline7×2=14-7 \times 2 = -14\newline7+2=5-7 + 2 = -5
  3. Write the factored form: Write the factored form using the two numbers found in Step 22.\newlineThe quadratic expression x25x14x^2 - 5x - 14 can be factored as (x7)(x+2)(x - 7)(x + 2).
