Tangents are drawn to `x^(2)+y^(2)=1` from any arbitrary point P on the line `2x+y-4=0`.Prove that corresponding chords of contact pass through a fixed point and find that point.

The tangents are drawn to x^(2)+y^(2)=1 from any arbitary point P on the line 2x+y-4=0. The corresponding chord of contact passes through a fired point B equation of parabola with focus s and directrix x-y=0 is
