👉 In mathematics, a quadric is a plane curve that is defined by an equation of the form: \[ax^2 + bxy + cy^2 + dx + ey + f = 0\] where \(a\), \(b\), \(c\), \(\Delta\) and \(d\) are constants. Quadrics are important in geometry as they can be used to model various geometric shapes such as planes, cylinders, ellipses, hyperboloids, and spheres.
