    Answer:

    x = ± 10

    Step-by-step explanation:

    Given

    f(x) = 8x² – 800

    To find the zeros let f(x) = 0, that is

    8x² – 800 = 0 ( add 800 to both sides )

    8x² = 800 ( divide both sides by 8 )

    x² = 100 ( take the square root of both sides )

    x = ± \sqrt{100} = ± 10

    Thus

    smaller solution is x = – 10

    larger solution is x = 10
