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 CalculatorĪbout solving equations A value is said to be a root of a polynomial if.Get immediate feedback and guidance with step-by-step solutions and Wolfram Problem Generator ![]() Here are some examples illustrating how to formulate queries. To avoid ambiguous queries, make sure to use parentheses where necessary. ![]() It also factors polynomials, plots polynomial solution sets and inequalities and more.Įnter your queries using plain English. In a future blog post, we’ll show you how Wolfram|Alpha can also solve inequalities and systems of inequalities. Remember that these are just a few of the ways that Wolfram|Alpha can solve equations-try some of your own math problems and explore other equation types. ![]() The underlying technology used here are the Mathematica functions FindInstance, Solve, RSolve, FindRoot, NSolve and Reduce. Do you need to solve a system of polynomial congruences? Wolfram|Alpha is not stumped!Īre you working with recurrence relations? Wolfram|Alpha can solve recurrence equations in seconds.įor more, check out the Examples pages. In the near future, it will be possible to see step-by-step solutions for systems of linear equations ![]() Wolfram|Alpha can also solve systems of linear and nonlinear equations. Of course, some solutions are too large or cannot be represented in terms of radicals Wolfram|Alpha will then return numerical solutions with a “More digits” button.Ĭonveniently, Wolfram|Alpha not only solves polynomial equations but also equations involving trigonometric, hyperbolic, or even special functions, as in the following example.ĭo you want to solve an equation over the reals? Just tell Wolfram|Alpha to restrict the domain. Wolfram|Alpha can also solve cubic and quartic equations in terms of radicals. What if the roots of the equation are complex? No worries Wolfram|Alpha has no trouble solving equations over the complex plane. Wolfram|Alpha can easily solve linear and quadratic equations, and even allows you to view a step-by-step solution of each problem. So next time you are stumped on an equation, consult Wolfram|Alpha for a little help. Wolfram|Alpha can solve equations from middle school level all the way through college level and beyond. Need a tutor for solving equations? Solving equations is just one of hundreds of mathematical tasks that can be done using Wolfram|Alpha.
