The polynomial function equation and the value of .

Let f(x) be the polynomial function.

So, the polynomial function .

The number zero is included for missing term in the dividend.

The remainder is r = 0.

Since the is the solution of the polynomial function, and is a factor.

The resulting quadratic expression factors as .

The complete factorization of polynomial function equation is .

Find the real zeros.

Solve .

; ; .

Thus, the real zeros are , , and .

The factor form of polynomial is and the solutions are , and .
