\frac{\left(x^{2}-5x\right)\left(x^{2}+x+5\right)}{\left(x-1\right)\left(x^{2}+x+5\right)}-\frac{\left(x^{2}-25\right)\left(x-1\right)}{\left(x-1\right)\left(x^{2}+x+5\right)}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x-1 and x^{2}+x+5 is \left(x-1\right)\left(x^{2}+x+5\right). Multiply \frac{x^{2}-5x}{x-1} times \frac{x^{2}+x+5}{x^{2}+x+5}. Multiply \frac{x^{2}-25}{x^{2}+x+5} times \frac{x-1}{x-1}.
\frac{\left(x^{2}-5x\right)\left(x^{2}+x+5\right)-\left(x^{2}-25\right)\left(x-1\right)}{\left(x-1\right)\left(x^{2}+x+5\right)}
Since \frac{\left(x^{2}-5x\right)\left(x^{2}+x+5\right)}{\left(x-1\right)\left(x^{2}+x+5\right)} and \frac{\left(x^{2}-25\right)\left(x-1\right)}{\left(x-1\right)\left(x^{2}+x+5\right)} have the same denominator, subtract them by subtracting their numerators.
