Time-saving video that defines and explains rational expressions video explanation and example problems finding the domain and excluded values of various rational expressions concept explanation. So the domain of $$\displaystyle \frac{{x+1}}{{2x(x-2)(x+3)}}$$ is $$\{x:x\ne -3,\,\,0,\,\,2\}$$ this means if we ever get a solution to an equation that contains rational expressions and has variables in the denominator (which they probably will), we must make sure that none of our answers would make any denominator in that equation “ 0. Here are the steps required for finding the domain of a rational function.

The first step in simplifying a rational expression is to determine the domain, the set of all possible values of the variables the denominator in a fraction cannot be zero because division by zero is undefined. Algebra domains of rational functions rational expressions are fractions with polynomials in both the numerator and denominator if the rational expression is a function, it is a rational function.
