To factor the quadratic expression , we need to find two numbers that multiply to and add up to .Let's analyze the given options:1. \((x-9)(x+2)\) - Multiplying: \((x-9)(x+2) = x^2 + 2x - 9x - 18 = x^2 - 7x - 18\) - This does not match .2. \((x+9)(x-7)\) - Multiplying: \((x+9)(x-7) = x^2 - 7x + 9x - 63 = x^2 + 2x - 63\) - This does not match .3. \((x-2)(x+9)\) - Multiplying: \((x-2)(x+9) = x^2 + 9x - 2x - 18 = x^2 + 7x - 18\) - This does not match .4. \((x-9)(x+7)\) - Multiplying: \((x-9)(x+7) = x^2 + 7x - 9x - 63 = x^2 - 2x - 63\) - This matches .Therefore, the correct factorization is \((x-9)(x+7)\).
