11-155.

Explain why it is useful to make *C* = 0 in the general quadratic relation *Ax*^{2} + *By*^{2} + *Cxy* + *Dx* + *Ey* + *F* = 0. Homework Help ✎

Suppose *C* ≠ 0.

What effect does this have on the process of factoring or manipulating this relation to look like the equation for a conic section?
