y^(2)-21y+90

If the line y=m x is outside the circle x^(2)+y^(2)-20 y+90=0 then

If 12sinx+5cosx=2y^(2)-8y+21 , to get values of x and y is

x^2-21 x+90

(y^(2)-90y+2000)/(y-50)

If the equation k^(2)x^(2)+10xy+3y^(2)-15x-21y+18=0 represents a pair of mutually perpendicular lines then

If the straight line y = mx is outside the circle x^2+y^2-20y+90=0 , then

Solve for x and y12sin x-2y^(2)=21-8y-5cos x
