    8 feet.

    Step-by-step explanation:

    To solve this, we can use solve for the width by factoring. If factors of - 112 are determined, we can find that - 8 and 14 are factors that sum up to the mid-term coefficient, or b. Therefore, we get:

    (x - 8) (x + 14) = 0.

    Take the positive zero from this factored equation, which is 8. Therefore, 8 feet is the width of the pool.
