Expert Answer
This question can be solved only if we assume the given polynomial is :- p(x) = x4 -6x3 -26x2 +140x -35
let α = 2+√3 and β = 2-√3 are roots of p(x). Then (x-α)(x-β) = x2 -(α+β)x + (αβ) = x2 -4x +1 is the factor of p(x)
If we divide p(x) by x2 -4x +1 we get quotient (x2 -2x + 35) . This quotient is factorised as (x-7)(x+5)
Hence other roots are 7 and -5
