Question

Find the zeros of the polynomial x power 4 + x cube - 34 x square minus 4x + 120 if two zeros are 2 and minus 2

Answer 1

let x⁴+x³-34x²-4x+120=p(x)

x=2 so x-2 is also a zero
similarly,x+2 is also a zero

so the product of the zeroes will also be zero
(x-2)(x+2)
=x²-2²=x²-4


Now divide x²-4 from p(x) now whatever the answer is Factories it using splitting middle term

Then you know what you have to do.

Answer 2

Step-by-step explanation:

all other zeros are :- 2,-2,-6,5
