What function has real zeros at x=10 and x=2?

f(x) = x² - 12x + 20

Step-by-step explanation:

Given the zeros of a polynomial f(x), say x = a, x = b

Then the factors are (x - a) and (x - b)

The function is then the product of the factors, that is

f(x) = (x - a)(x - b)

Here the zeros are x = 10 and x = 2, thus

The factors are (x - 10) and (x - 2) , and the function is

f(x) = (x - 10)(x - 2) ← expand factors using FOIL

     = x² - 2x - 10x + 20

     = x² - 12x + 20
