all conic equations are quadratics

anonymous · Answer

A quadratic equation is an equation where there is a variable that is raised to the 2nd power - like this:  x^2   On a graph, this will be a parabola (just a fancy name for a curve)

amistre64 · Answer

x^3 + y^2 = 3 is not a quadratic tho; even tho there is a variable raised to the 2nd power

amistre64 · Answer

xy+3 = 5 is a quadratic since the highest degree of any term is 2

so it can only be raised to the second power?
