(x - 9)(x + 11). This is the factorization of a quadratic equation by using the quadratic equation. The factors of the expression -99 are (-9 and 11). To get these factors, the equation needs to be rearranged to take the form of 0 = ax^2 + bx + c. In this case, a=1, b=-2, and c=-99. Then, you take the two factors of -99 and set each equal to 0 and solve for x. Then, the equation can be rewritten as (x - 9)(x + 11) to get the final factorization.
