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

Answer :

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 f(x) by (x - 2)(x + 2) = x2 - 4 to find other zeros.



By applying division algorithm, we have:


Hence, two other zeroes are -6 and 5
