\frac{3x^{5}-5x^{3}}{15}
Factor out \frac{1}{15}.
x^{3}\left(3x^{2}-5\right)
Consider 3x^{5}-5x^{3}. Factor out x^{3}.
\frac{x^{3}\left(3x^{2}-5\right)}{15}
Rewrite the complete factored expression. Polynomial 3x^{2}-5 is not factored since it does not have any rational roots.
\frac{3x^{5}}{15}-\frac{5x^{3}}{15}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 5 and 3 is 15. Multiply \frac{x^{5}}{5} times \frac{3}{3}. Multiply \frac{x^{3}}{3} times \frac{5}{5}.
\frac{3x^{5}-5x^{3}}{15}
Since \frac{3x^{5}}{15} and \frac{5x^{3}}{15} have the same denominator, subtract them by subtracting their numerators.
