complex rational expression | A complex rational expression is a rational expression in which the numerator and/or denominator contains a rational expression. | ||||
critical point of a rational inequality | The critical point of a rational inequality is a number which makes the rational expression zero or undefined. | ||||
extraneous solution to a rational equation | An extraneous solution to a rational equation is an algebraic solution that would cause any of the expressions in the original equation to be undefined. | ||||
proportion | When two rational expressions are equal, the equation relating them is called a proportion. | ||||
rational equation | A rational equation is an equation that contains a rational expression. | ||||
rational expression | A rational expression is an expression of the form \(\frac{p}{q}\), where \(p\) and \(q\) are polynomials and \(q≠0\). | ||||
rational function | A rational function is a function of the form \(R(x)=\frac{p(x)}{q(x)}\) where \(p(x)\) and \(q(x)\) are polynomial functions and \(q(x)\) is not zero. | ||||
rational inequality | A rational inequality is an inequality that contains a rational expression. | ||||
similar figures | Two figures are similar if the measures of their corresponding angles are equal and their corresponding sides have the same ratio. | ||||
simplified rational expression | A simplified rational expression has no common factors, other than \(1\), in its numerator and denominator. |
