    Answer:

    x^2 -12x+20

    Step-by-step explanation:

    If the zeros of the functions are at 10 and 2

    (x-10) (x-2)

    FOIL

    x^2 -2x-10x+20

    Combine like terms

    x^2 -12x+20

    Answer:

    First one:

    f(x) = x2 – 12x + 20

    Step-by-step explanation:

    Factors:

    (x – 10)(x – 2)

    x² – 10x – 2x + 20

    x² – 12x + 20
