\frac{x+5}{2\left(x-1\right)}-\frac{1}{\left(x-2\right)\left(x-1\right)}-\frac{1}{x^{2}-4x+4}

\frac{\left(x+5\right)\left(x-2\right)}{2\left(x-2\right)\left(x-1\right)}-\frac{2}{2\left(x-2\right)\left(x-1\right)}-\frac{1}{x^{2}-4x+4}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2\left(x-1\right) and \left(x-2\right)\left(x-1\right) is 2\left(x-2\right)\left(x-1\right). Multiply \frac{x+5}{2\left(x-1\right)} times \frac{x-2}{x-2}. Multiply \frac{1}{\left(x-2\right)\left(x-1\right)} times \frac{2}{2}.
\frac{\left(x+5\right)\left(x-2\right)-2}{2\left(x-2\right)\left(x-1\right)}-\frac{1}{x^{2}-4x+4}
