Answer
$\displaystyle \frac{x^{2}}{15}$
Work Step by Step
When multiplying rational expressions, we
- fully factor each numerator and denominator (here, no need)
- reduce the expression if there are common factors (here: none)
- multiply all the numerators, multiply all the denominators.
$\displaystyle \frac{x}{5}\cdot\frac{x}{5}=\frac{x\cdot x}{5\cdot 3}$ = $\displaystyle \frac{x^{2}}{15}$
