\frac{2x^{3}}{x^{3}\left(x-1\right)^{3}}-\frac{2\left(x-1\right)^{3}}{x^{3}\left(x-1\right)^{3}}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of \left(x-1\right)^{3} and x^{3} is x^{3}\left(x-1\right)^{3}. Multiply \frac{2}{\left(x-1\right)^{3}} times \frac{x^{3}}{x^{3}}. Multiply \frac{2}{x^{3}} times \frac{\left(x-1\right)^{3}}{\left(x-1\right)^{3}}.
\frac{2x^{3}-2\left(x-1\right)^{3}}{x^{3}\left(x-1\right)^{3}}
Since \frac{2x^{3}}{x^{3}\left(x-1\right)^{3}} and \frac{2\left(x-1\right)^{3}}{x^{3}\left(x-1\right)^{3}} have the same denominator, subtract them by subtracting their numerators.
