Question

For the circle x² + y² + 6x – 4y + 3 = 0, find the equation of the tangent at
(–2, 5).

Answer 1

use the formula :
(x-x1)(x-h) + (y-y1)(y-k) = r^2

with (x1, y1) is the point of tangent line and
h,k is the centre of circle
r is radius of circle

Answer 2

do u know how to get the centre and the radius of that circle ?
