The point (1, 4) lie ___________ the circle x^2+y^2-2x-4y+2=0.(a) inside circle(b) outside circle(c) on the circle(d) either inside or outsideThis question was addressed to me in examination.The doubt is from Conic Sections topic in chapter Conic Sections of Mathematics – Class 11

Answer»

Right OPTION is (b) outside CIRCLE

To explain I WOULD say: Circle has equation x^2+y^2-2x-4y+2=0.

1^2+4^2-2*1-4*4+2 = 1+16-2-16+2 =1 > 0 so, point is outside the circle.
