If the cirles `x^2+y^2=2` and `x^2+y^2-4x-4y+lambda=0` have exactly three real common tangents then `lambda=`

the no.of possible integral values of m for which the circle x^(2)+y^(2)=4 and x^(2)+y^(2)-6x-8y+m^(2)=0 has exactly two common tangents are

The range of values of lambda for which the circles x^(2)+y^(2)=4 and x^(2)+y^(2)-4lambda x + 9 = 0 have two common tangents, is

If the two circles x^(2) + y^(2) =4 and x^(2) +y^(2) - 24x - 10y +a^(2) =0, a in I , have exactly two common tangents then the number of possible integral values of a is :

The intercepts made by the line y=x+lambda on the circles x^(2)+y^(2)-4=0 and x^(2)+y^(2)-10x-14y+65=0 are equal,then the value of 2 lambda-3 is

If the equation x^(2)+y^(2)+2 lambda x+4=0 and x^(2)+y^(2)-4 lambda y+8=0 represent real circles then the valueof lambda can be

If 2x-3y=0 is the equation of the common chord of the circles x^(2)+y^(2)+4x=0 and x^(2)+y^(2)+2 lambda y=0 then the value of lambda is

If the circle x^(2)+y^(2)-4x-6y+lambda=0 touches the axis of x, then determine the value of lambda and the point of contact
