If a line with positive alope passing through `P(0,1)` intersects the curve `y=x^2-x` at `A=P` that `PA.PB=2,` then `AB` is

If a line with positive slope passing through point P(0,1) interesects the curve y=x^(2)-x at A and B such that PA.PA=2, then AB is:

If the line passing through P=(8,3) meets the circle S-=x^(2)+y^(2)-8x-10y+26=0 at A,B then PA.PB=

If the line passing through P=(8,3) meets the circle S-=x^(2)+y^(2)-8x-10y+26=0 at A,B then PA.PB=

A line passing through P(1,2) intersect the line x+y+3=0 in point A such that AP=3sqrt(2) then slope of AP is

A line passing through (1,0) intersects the curve 2x^(2)+5y^(2)-7x=0 in A and B then the angle substended by the line AB at the origin is

If a line through P(-2,3) meets the circle x^(2)+y^(2)-4x+2y+k=0 at A and B such that PA.PB=31 then the radius of the circles is

If a line through P(-2,3) meets the circle x^(2)+y^(2)-4x+2y+k=0 at A and B such that PA.PB =31 then the radius of the circle is

If a line through P(-2,3) meets the circle x^(2)+y^(2)-4x+2y+k=0 at A and B such that PA.PB=31 then the radius of the circles is

If a line passes through the point P(1,-2) and cuts the x^2+y^2-x-y= 0at A and B, then themaximum of PA+PB is
