A polynomial function has zeros at 5 and - 7 and 0. Write a function in standard form that could represent this function

If the poly's zeros are 5, - 5 and 0, then the corresponding factors are

(x-5) (x+7) (x), and the function is f (x) = (x-5) (x+7) (x).

You must multiply this out and arrange the resulting terms in descending order by powers of x.
