Simplify the complex fraction. 1−1x2−3y
To simplify the complex fraction $1-\frac{1}{x^2-3y}$, we need to find a common denominator for the terms in the fraction.
The common denominator for $1$ and $\frac{1}{x^2-3y}$ is $x^2-3y$.
Thus, the expression can be rewritten as $\frac{x^2-3y}{x^2-3y}-\frac{1}{x^2-3y}$.
Simplifying further, we get $\frac{x^2-3y-1}{x^2-3y}$.
