Quadratic Equation

Quadratic Equation is an equation which contains an `x^2` term (or if you want to get technical it is an equation containing a single variable of degree2 with no higher power).

Example 1

A quadratic equation is an equation which contains a `x^2` term.






All of the equations contain a `x^2` term therefore they are called quadratic equations.


Example 2


This is a well known quadratic equation i.e. containing `x^2`


Example 3



These are NOT quadratics because the first has another variable with degree squared and the second has one with a higher power than 2.
