Find the vertex,focus,axis,directrix and latus rectum of the following parabola: y^(2)-4y-3x+1=0

Find the vertex , focus, axis, directrix and latus rectum of the following parabola: y^2-4y-3x+1=0

Show that the line 3x-4y=1 touches the circle x^(2)+y^(2)-2x+4y+1=0 .

For the circle x^(2)+y^(2)-2x-4y-4=0 ,the lines 2x+3y-1=0,2x+y-1=0 are

The equation of the circle is 3x^(2) + 3y^(2)+6x-4y -1=0 . Then its radius is

The circles x^(2)+y^(2)-2x-4y+1=0 and x^(2)+y^(2)+4y-1 =0

Find the centre and radius of each of the following circle : (i) x^(2)+y^(2)+4x-4y+1=0 (ii) 2x^(2)+2y^(2)-6x+6y+1=0 (iii) 2x^(2)+2y^(2)=3k(x+k) (iv) 3x^(2)+3y^(2)-5x-6y+4=0 (v) x^(2)+y^(2)-2ax-2by+a^(2)=0

The circles x^(2)+y^(2)-2x-4y+1=0 and x^(2)+y^(2)+4x+4y-1=0 touch internally touch externally have 3x+4y-1=0 as the common tangent at the point of contact have 3x+4y+1=0 as the common tangent at the point of contact

x^(2) - 1 = 0, y^(2) + 4y + 3 = 0

If (1,2)(2,a) are extremities of a diameter of the circle x^(2)+y^(2)-3x-4y+6=0 then a=
