Detailed Solution

Let (h, k) be the point of intersection of the tangents. Then, the chord of contact of tangents is the common chord of the circles x2+y2=12 and x2+y2−5x+3y−2=0The equation of the common chord is 5x−3y−10=0Also, the equation of the chord of contact ishx+ky−12=0Equations (i) and (ii) represent the same line. Therefore, h5=k−3=−12−10⇒h=6,k=−18/5Hence, the required point is (6,−18/5).
