An equation is a mathematical statement, in symbols, that two things are the same (or equivalent). Equations are written with an equal sign. Equations are often used to state the equality of two expressions containing one or more variables.

An expression is a combination of numbers, operators, grouping symbols (such as brackets and parentheses) and/or free variables and bound variables arranged in a meaningful way which can be evaluated. Bound variables are assigned values within the expression (they are for internal use) while free variables can take on values from outside the expression.

In mathematics, a quadratic equation is a polynomial equation of the second degree. The general form is

*a*x^{2} + *b*x + *c* = 0

where a ≠ 0. (For a = 0, the equation becomes a linear equation.)

The letters*a*, *b*, and *c* are called coefficients: the quadratic coefficient *a* is the coefficient of x^{2}, the linear coefficient *b* is the coefficient of x, and *c* is the constant coefficient, also called the free term or constant term.

Quadratic equations are called quadratic because quadratus is Latin for "square"; in the leading term the variable is squared.

where a ≠ 0. (For a = 0, the equation becomes a linear equation.)

Quadratic equations are called quadratic because quadratus is Latin for "square"; in the leading term the variable is squared.

The radical symbol is used to indicate the nth root of a number.
