To find the domain, factor the expression and then identify which values of x will result in a denominator of 0 before simplifying. In this expression, $\displaystyle\frac{{{5}{{x}}^{{3}}+{15}{{x}}^{{2}}+{10}{x}}}{{{3}{{x}}^{{3}}-{3}{x}}}=\frac{{{5}{x}{\left({x}+{2}\right)}{\left({x}+{1}\right)}}}{{{3}{x}{\left({x}-{1}\right)}{\left({x}+{1}\right)}}}\usepackage{cmbright}\Huge\$ . What values of x are not included in the domain?
