What is the equation of the tangent to the circle (x-5)^2+(y-3)^2=9 at the points of intersection of the circle with the line 2x-y-1=0

Teh points of intersection can be found by subbing in y=2x-1 to the equation of the circle. (x-5) 2 +(2x-1-3) 2 =5x 2 -26x+33=9 so we have 5x 2 -26x+24=0. Solving the quadratic equation gives x 1 =4 and x 2 ...
