Quadratic Expressions

An algebraic expression having the degree of '2' is called a quadratic expression. By 'degree', we mean the highest exponent on the variable/s in an algebraic expression.

For example, `x^2 + 2x + 3` is an algebraic expression in which the variable `x` has the highest exponent of `2`.

Quadratic expressions can be written in various forms, namely the General Form, the Vertex Form and the Intercept Form. A quadratic expression can be converted from one form to another by using algebraic operations.

A quadratic expression can be factored into a product of two linear expressions by the method of splitting the middle term.
