Answer 2

Hey here is your answer

$\frac{x - 1}{2x + 1} - \frac{2x + 1}{x - 1} \\ \\ \frac{(x - 1)(x - 1) - (2x + 1)(2x + 1)}{(2x + 1)(x - 1)} \\ \\ \frac{ {(x - 1)}^{2} - {(2x + 1)}^{2} }{2x(x - 1) + 1(x - 1)} \\ \\ \frac{ {x}^{2} + {1}^{2} - 2 \times x \times 1 - {(2x)}^{2} - {1}^{2} - 2 \times 2x \times 1 }{2 {x}^{2} - 2x + x - 1} \\ \\ \frac{ {x}^{2} + 1 - 2x - 4 {x}^{2} - 1 - 4x }{2 {x}^{2} - x - 1 } \\ \\ \frac{ - 3 {x}^{2} - 6x }{2 {x}^{2} - x - 1}$
