Find all the zeros of the polynomial , if two of its zeros are 2 and-2.

We know that if is a zero of a polynomial then


Since -2 and 2 are zeros of Therefore and are factors of .


Now on dividing to find other zeros.



By applying division algorithm, we have:


= ()


= ()


= {}


Hence, the zeros of the given polynomial are:
