\frac{5\left(x+1\right)}{x\left(x+1\right)}-\frac{\left(3x+2\right)x}{x\left(x+1\right)}+\frac{2}{x^{2}+x}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x and x+1 is x\left(x+1\right). Multiply \frac{5}{x} times \frac{x+1}{x+1}. Multiply \frac{3x+2}{x+1} times \frac{x}{x}.
\frac{5\left(x+1\right)-\left(3x+2\right)x}{x\left(x+1\right)}+\frac{2}{x^{2}+x}
Since \frac{5\left(x+1\right)}{x\left(x+1\right)} and \frac{\left(3x+2\right)x}{x\left(x+1\right)} have the same denominator, subtract them by subtracting their numerators.
