\frac{\frac{2x}{x^{2}}+\frac{5}{x^{2}}}{\frac{4}{x^{2}}-\frac{25}{x}}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x and x^{2} is x^{2}. Multiply \frac{2}{x} times \frac{x}{x}.
\frac{\frac{2x+5}{x^{2}}}{\frac{4}{x^{2}}-\frac{25}{x}}
Since \frac{2x}{x^{2}} and \frac{5}{x^{2}} have the same denominator, add them by adding their numerators.
\frac{\frac{2x+5}{x^{2}}}{\frac{4}{x^{2}}-\frac{25x}{x^{2}}}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x^{2} and x is x^{2}. Multiply \frac{25}{x} times \frac{x}{x}.
\frac{\frac{2x+5}{x^{2}}}{\frac{4-25x}{x^{2}}}
Since \frac{4}{x^{2}} and \frac{25x}{x^{2}} have the same denominator, subtract them by subtracting their numerators.
\frac{\left(2x+5\right)x^{2}}{x^{2}\left(4-25x\right)}
Divide \frac{2x+5}{x^{2}} by \frac{4-25x}{x^{2}} by multiplying \frac{2x+5}{x^{2}} by the reciprocal of \frac{4-25x}{x^{2}}.
\frac{2x+5}{-25x+4}
Cancel out x^{2} in both numerator and denominator.
