\frac{\frac{5x}{x}+\frac{6}{x}}{1-\frac{4}{x^{2}}}
To add or subtract expressions, expand them to make their denominators the same. Multiply 5 times \frac{x}{x}.
\frac{\frac{5x+6}{x}}{1-\frac{4}{x^{2}}}
Since \frac{5x}{x} and \frac{6}{x} have the same denominator, add them by adding their numerators.
\frac{\frac{5x+6}{x}}{\frac{x^{2}}{x^{2}}-\frac{4}{x^{2}}}
To add or subtract expressions, expand them to make their denominators the same. Multiply 1 times \frac{x^{2}}{x^{2}}.
\frac{\frac{5x+6}{x}}{\frac{x^{2}-4}{x^{2}}}
Since \frac{x^{2}}{x^{2}} and \frac{4}{x^{2}} have the same denominator, subtract them by subtracting their numerators.
\frac{\left(5x+6\right)x^{2}}{x\left(x^{2}-4\right)}
Divide \frac{5x+6}{x} by \frac{x^{2}-4}{x^{2}} by multiplying \frac{5x+6}{x} by the reciprocal of \frac{x^{2}-4}{x^{2}}.
\frac{x\left(5x+6\right)}{x^{2}-4}
Cancel out x in both numerator and denominator.
\frac{5x^{2}+6x}{x^{2}-4}
Use the distributive property to multiply x by 5x+6.
