Question

hey frnds pls solve this

Answer 1

Let a and b be -√5/2,√5/2
(x-√5/2)(x+√5/2)=x2-5/2
P(x)=8x4+8x3-18x2-20x-5
On dividing p(x) by x2-5/2
(x2-5/2=2x2-5)
The answer is 4x2+4x+1

Then fectorize the answer
4x2+2x+2x+1
2x(2x+1)+1(2x+1)
(2x+1)(2x+1)
x =-1/2,-1/2
Therefore, the zeros are -1/2,-1/2

I hope it's help u please mark as brainliest if u like my answer
