Answer:

f (x) = (x-4)(x + 5)^2(x-9)(x+7)

Step-by-step explanation:

The zeros of the polynomial are all the values of x for which the function f (x) = 0

In this case we know that the zeros are:

x = 4,\ x-4 =0

x = 9,\ x-9=0

x = -5, x + 5 = 0 (multiplicity 2)

x = -7,\ x+7=0

Now we can write the polynomial as a product of its factors

f (x) = (x-4)(x + 5)^2(x-9)(x+7)

Note that the polynomial is of degree 5 because the greatest exponent of the variable x that results from multiplying the factors of f (x) is 5
