WebThe determinant of the equation is B 2 - 4AC. Assuming a conic is not degenerate, the following conditions hold true: If B 2-4AC > 0, the conic is a hyperbola. If B 2-4AC < 0, the conic is a circle, or an ellipse. If B 2 - 4AC = 0, the conic is a parabola. Another way to classify conics has to do with the product of A and C. WebDeterminant of a Matrix.
