x=1/2-√3

=> 2x-√3x=1

=> 2x-1=√3x

squaring on both the sides

=> 4x² + 1-4x = 3x²

=> x²-4x+1=0=q(x)...[say]....................(1)

divide this equation by x³ - 2x²-7x+5=p(x)....[say]

=>p(x)=q(x).(x+2)+3..                                                  [please solve it]

          from(1)

            =0.(x+2)+3

            =3 ans.
