    Answer:

    x = 7, x = -2

    Step-by-step explanation:

    (x-7) (x+2) = 0

    Zero product property: In order to get a product (the answer to a multiplication problem) of 0, you need to have at least one of the numbers being multiplied be 0. For example, in x * y = 0, either x or y needs to be equal to 0.

    Using this, we know that either (x – 7) or (x + 2) is 0. So,

    x – 7 = 0

    Add 7 to both sides.

    x = 7

    x + 2 = 0

    Subtract 2 from both sides.

    x = – 2

    So, the answer is x = 7 or x = -2
