    Hello:

    all quadratic function f whose zeros are 11 and 3 is:

    f (x) = a (x-11) (x-3) ... a ≠ 0

    for exemple : f (x) = 4 (x-11) (x-3)

    Let the variable of the equation be x.

    I'm gonna go backwards of the factorization process.

    Given,

    x = 11 or 3

    (x - 11) (x - 3) = 0

    x² - 3x - 11x + 33 = 0

    x² - 14x + 33 = 0

    Hence, f (x) = x² - 14x + 33.
