Unless you are sure whether an expression is quadratic or not, you will not be able to apply an appropriate method to solve it. Further, sometimes it may prove difficult to identify whether an algebraic expression is quadratic or not. This post is written to help you identify whether an algebraic expression is a valid quadratic expression or not.

Basic Steps of Identifying Quadratic Expressions:

The following expressions may not appear to be quadratic expressions at the first glance:

Basic Steps of Identifying Quadratic Expressions:

**Simplify the expression (opposite of factoring)****Find the greatest exponent on a variable in the expression****If the greatest exponent is 2 it is a quadratic expression**

__. The following examples will guide you on how to simplify an expression.__**no products should be left unmultiplied**The following expressions may not appear to be quadratic expressions at the first glance:

- x(x + 3)
- (x
^{3}+ 2x) / 3x - (y
^{3}x^{3}+ x^{2}y^{2}) / xy

- x
^{2}+ 3x - x
^{2}/3 + 2/3 - y
^{2}x^{2}+ xy

**greatest exponent in each expression is 2**.
