\frac{60}{x}+\frac{xx}{x}
To add or subtract expressions, expand them to make their denominators the same. Multiply x times \frac{x}{x}.
\frac{60+xx}{x}
Since \frac{60}{x} and \frac{xx}{x} have the same denominator, add them by adding their numerators.
\frac{60+x^{2}}{x}
Do the multiplications in 60+xx.
