\frac{625\times 3}{3x}-\frac{xx}{3x}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x and 3 is 3x. Multiply \frac{625}{x} times \frac{3}{3}. Multiply \frac{x}{3} times \frac{x}{x}.
\frac{625\times 3-xx}{3x}
Since \frac{625\times 3}{3x} and \frac{xx}{3x} have the same denominator, subtract them by subtracting their numerators.
\frac{1875-x^{2}}{3x}
Do the multiplications in 625\times 3-xx.
