Factor denominators $\frac{x}{(x+1)(x-1)} + \frac{6x}{x(1-x)}$ cancel x"s .... pull out a neg from 2nd denominator $\frac{x}{(x+1)(x-1)} - \frac{6}{x-1}$ Notice both denominators share the factor (x-1) To make denominators the same multiply 2nd fraction by (x+1)/(x+1) $\frac{x}{(x+1)(x-1)} - \frac{6(x+1)}{(x+1)(x-1)}$ Now combine fractions... add like terms on top $\frac{x -6x-6}{(x+1)(x-1)}$ $\frac{-5x-6}{(x+1)(x-1)}$
