−4x+3y−1=0.

Let the point of intersection of tangents by p(h,k)

Line AB 2x+y+12=0 is chord of contact

Equation of chord of contact is given by:

x(h)+y(k)−4(

⇒xh+yk−2x−2h+

Comparing this with given equation 2x+y+12=0

4h−3k+2

)

Solving, we get

h=1,k=−2

(1,−2).

on this process we can solve
