Answer 1

$frac{5}{b + 2} - frac{1}{b} \ \ frac{5b - (b + 2)}{b times (b + 2)} \ \ frac{5b - b - 2}{b times (b + 2)} \ \ frac{5b - b - 2}{b {}^{2} + 2b } \ \ frac{5b - b - 2}{b {}^{2} + 2b} \ \ frac{4b {}^{2} - 2}{b {}^{2} + 2b} \ \ \ \ 2) frac{x {}^{2} - 3xy }{x {}^{2} - y {}^{2} } + frac{y}{x - y} \ \ frac{x {}^{2} - 3xy}{(x - y) times (x + y)} + frac{y}{x - y} \ \ frac{x {}^{2} - 3xy + y times (x + y) }{(x - y) times (x + y)} \ \ frac{x { }^{2} - 3xy + xy + y {}^{2} }{(x - y) times (x + y)} \ \ frac{x {}^{2} - 2xy + y {}^{2} }{(x - y) times (x + y)} \ \ frac{(x - y) {}^{2} }{(x - y) times (x + y)} \ \ frac{x - y}{x + y}$
