    If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:

    (x - 2) * (x + 5) = 18

    x^2 + 5x - 2x - 10 = 18

    x^2 + 3x - 28 = 0

    (x + 7) * (x - 4) = 0

    1. x = - 7

    2. x = 4

    The correct result would be x = - 7.
