In some cases, linear algebra methods such as Gaussian elimination are used, with optimizations to increase speed and reliability. How Wolfram|Alpha solves equationsДЇor equation solving, Wolfram|Alpha calls the Wolfram Language's Solve and Reduce functions, which contain a broad range of methods for all kinds of algebra, from basic linear and quadratic equations to multivariate nonlinear systems. Similar remarks hold for working with systems of inequalities: the linear case can be handled using methods covered in linear algebra courses, whereas higher-degree polynomial systems typically require more sophisticated computational tools. More advanced methods are needed to find roots of simultaneous systems of nonlinear equations. This too is typically encountered in secondary or college math curricula.

Systems of linear equations are often solved using Gaussian elimination or related methods. These use methods from complex analysis as well as sophisticated numerical algorithms, and indeed, this is an area of ongoing research and development. There are more advanced formulas for expressing roots of cubic and quartic polynomials, and also a number of numeric methods for approximating roots of arbitrary polynomials.

One also learns how to find roots of all quadratic polynomials, using square roots (arising from the discriminant) when necessary. One learns about the 'factor theorem,' typically in a second course on algebra, as a way to find all roots that are rational numbers. This polynomial is considered to have two roots, both equal to 3. To understand what is meant by multiplicity, take, for example. If has degree, then it is well known that there are roots, once one takes into account multiplicity. The largest exponent of appearing in is called the degree of. Partial Fraction Decomposition CalculatorДЄbout solving equations A value is said to be a root of a polynomial if.
