-\frac{1}{a}-\frac{a}{a}>1
To add or subtract expressions, expand them to make their denominators the same. Multiply 1 times \frac{a}{a}.
\frac{-1-a}{a}>1
Since -\frac{1}{a} and \frac{a}{a} have the same denominator, subtract them by subtracting their numerators.
\frac{1}{a}\left(-2a-1\right)>0
Factor out a.
