The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.
A quadratic can be used to represent many different things, such as parabolic/satellite dishes and the flight of ballistic projectiles.

A quadratic equation has two roots. They may be similar or dissimilar. As the highest power of a quadratic equation is 2 , there are 2 roots. Similarly, in the cubic equation, the highest power is 3, so it has three equal or unequal roots. So the highest power of an equation is the answer to the no of roots of that particular equation.
There are many equations that are neither linear nor quadratic. A simple example is a cubic equation, such as y = x3, or a logarithmic equation, such as y = ln(x).

A quadratic equation has one discriminant.
If the discriminant of a quadratic equation is less then 0 then it will have no real solutions.

The quadratic has no real solutions.
Any quadratic equation has one discriminant.
the maximum number of solutions to a quadratic equation is 2. However, usually there is only 1.

As one example, the quadratic equation can be used to model many different phenomena - if you were to measure the height of a baseball as it was thrown straight up in the air and pulled down again, and plot the height with respect to time, it would look like a quadratic equation. Computer modelling is a large field with many applications in physics, meterology, and even social sciences.
