Question

For the circles x²+y²+2lamda x+c=0,x²+y²+2my-c=0 the number of common tangents when c not equal to c is​

Answer 1

If the cirles x^2+y^2=2 and x^2+y^2-4x- 4y+lambda=0 have exactly three real common ... The line `4y - 3x + lambda =0` touches the circle `x. play ... If `y = mx + c` be a tangent to the hyperbola ` x.
