An equation where the highest exponent of the variable (usually "x") is a square (

So it will have something like x

But

A Quadratic Equation is usually written a

Example: 2

^{2}).So it will have something like x

^{2}But

**not**x^{3}etc.A Quadratic Equation is usually written a

**x**+ b^{2}**x**+ c = 0Example: 2

**x**+ 5^{2}**x**− 3 = 0See: Exponent
