In mathematics, a quadratic is a type of problem that ... Notice these values are also the places at which the graph of the standard form of the equation (y = x² – x – 1) crosses the X ...

A quadratic graph is produced when you have an equation of the form \(y = ax^2 + bx + c\), where \(b\) and \(c\) can be zero but \(a\) cannot be zero. All quadratic graphs have a line of symmetry.
