How to Convert Quadratic Equations From Standard to Vertex Form?

The standard form of a quadratic equation is y = ax^2 + bx + c, where a, b, and c are coefficiencts and y and x are variables. It is easier to solve a quadratic equation when it is in standard form... Read More »

How to Convert an Equation Into Vertex Form?

Parabola equations are written in the standard form of y=ax^2+bx+c. This form can tell you if the parabola opens up or down and, with a simple calculation, can tell you what the axis of symmetry is... Read More »

How to Form a Quadratic Equation With No Intercepts?

The number of intercepts of a quadratic equation is determined by the value of its discriminant. If the discriminant is greater than zero, the function has two intercepts; if it is exactly zero, it... Read More »

How to Solve an Equation by Substitution in Quadratic Form?

A quadratic equation contains a variable of which the highest exponent is 2. For example, x^2 + x = - 1 is a quadratic equation because the highest exponent of x is 2. An equation that is quadratic... Read More »
