—2x—\d[zJ—x-\-^X, must represent a circle on the straight line, whose equation is 106 ANALYTICAL GEOMETRY. 1st. Construct that straight line BC. 2d. Put ±V—^^+4a;=0. Whence x=0, or 4. That is, the curve extends from theaxis of Fto the distance of plus 4, on theaxis of X. Now take P, the middle… … OTHER EXAMPLES. 1. Find or construct the curve repres<ented hy the equation3/2 _j.2^^_|_3^2_4^_-0. Whence ?/=—xztij—^x{x—2). If we make x=^0, we shall find y=0 at the same time, there-fore the curve passes through the origin A. In the original equation, if we make y=0 we shall have Whence x=^Qy…
