Question

If 2 and -2 are the two zeros of the polynomial (x4 + x3 -34 x2 -4x +120),find all the zeroes of the given polynomial.

Help me please !!

Answer 1

2 and -2 are zeros.
Therefore, (X-2) and (X+2) are factors of the p(X).
(X-2)*(X+2)=X^2-4.
now divide the polynomial with X^2-4.
You will obtain another equation as the quotient.
The roots of that equation with the above given roots are the answer.
Hope this helps.

P.S- Couldn't do the calculations here as it is my mobile.
