Just type in an equation and it will show you the solution
To solve a fractional equation, first try to eliminate the unknown variable out of the denominator and then solve the equation just like a normal equation. But keep in mind that a solution is not allowed to be a root of the denominator. (In that case you have a definition gap). A fractional equation is an equation containing fractional terms. To solve it, it makes sense to get rid of the fractional term by transformations. Then you treat it as a normal equation. Solving fractional equations often leads to quadratic equations.algebra two formula chart | simple fractions worksheets for kids | system equation calculator complex | exponential expressions | writing algebraic expressions free worksheets | factoring quadratic worksheet | dividing quadratic equations | how to plot points on a graphing calculator for 4 sets of data | cannot solve with ode45 in matlab | algebra 2 expressions and formulas cheat sheet worksheets
MINIMATH is an algebra web application for solving equations and simplifying expressions of monomials, multivariate polynomials and rational fractions (with integer or rational coefficients), showing all steps. A monomial can be typed by using a not ambiguous positional notation. For instance, the monomial (1/2)*(x^2)*c*(b^3) can be typed as follows: 1/2x2cb3 Only the following characters can be used for variables: a b c d e f g h i j k l m n o p q r s t u v w x y z In order to avoid ambiguity, upper case variables will be converted to lower case. In case decimals are typed, they will be automatically converted into fractions. Repeating decimals must be typed by using round brackets to indicate the repetend. For example: 0.58(3) or 0,58(3) will become 7/12 The symbols used to identify operators are the following: - exponentiation to an integer or rational exponent (^) - division/fraction (/), division (:), multiplication (*) - addition (+), subtraction (-) - square root of m (sqrt(m)), only if m is a perfect square - root n of m (root(n)(m)), only if n is an integer and m is a perfect power Greatest common divisor - GCD ($) and least common multiple - LCM (&) operators can be used to calculate one of the polynomials belonging to the GCD and LCM sets of a given couple of polynomials. EXAMPLE = (x4-9x2-4x+12)$(x3+5x2+2x-8) => calculates one greatest common divisor RESULT = x2+x-2 => the polynomial GCD is defined only up to the multiplication by an invertible constant The greatest common divisor is also called greatest common factor (GCF).
