In mathematics, a quadratic equation (from Latin quadratus 'square') is an equation that can be rearranged in standard form as a x 2 + b x + c = 0 , {\displaystyle ax^{2}+bx+c=0\,,} where x represents an unknown value, and a , b , and c represent known numbers, where a ≠ 0 .

A quadratic equation is an equation of degree 2 that involves a variable squared. Learn how to write quadratic equations in standard form, how to use the quadratic formula, and how to find real or complex solutions.
- Solving Quadratic Equations by Factoring. An equation containing a second-degree polynomial is called a quadratic equation. For example, equations such as \\(2x^2 +3x−1=0\\) and \\(x^2−4= 0\\) are quadratic equations.
- Solving Quadratics with a Leading Coefficient of \\(1\\) In the quadratic equation \\(x^2 +x−6=0\\), the leading coefficient, or the coefficient of \\(x^2\\), is \\(1\\).
- Factoring and Solving a Quadratic Equation of Higher Order. When the leading coefficient is not \\(1\\), we factor a quadratic equation using the method called grouping, which requires four terms.
- Using the Square Root Property. When there is no linear term in the equation, another method of solving a quadratic equation is by using the square root property, in which we isolate the \\(x^2\\) term and take the square root of the number on the other side of the equals sign.
