    Step-by-step explanation:

    Given that,

    0 = 0.25x² - 8x

    This is a quadratic equation, since it has the highest power of x to be 2.

    0.25x² - 8x = 0

    Simplify this by bring out x

    x (0.25x - 8) = 0

    So, if a * b = 0, it is either a = 0 or b = 0, if the multiplication of two number is 0, then it is either one of the number is 0 or both numbers is 0

    So,

    x (0.25x - 8) = 0

    x = 0. OR. 0.25x - 8 = 0

    x = 0. OR. 0.25x = 8

    x = 0. OR. x = 8 / 0.25

    x = 0. OR. x = 32.

    So, the solution that describe the system is

    0.25 (0) ² - 8 (0)

    OR

    0.25 (32²) - 8 (32)
