Answer 1

Смотри....................

Answer 2

$\frac{3x(x + 3) -x( x + 15 )- 2(x - 3)(x + 3)}{x(x - 3)(x + 3)}$

$\frac{3 {x}^{2} + 9 - {x}^{2} - 15x - 2 {x}^{2} + 18 }{x(x - 3)(x + 3)}$

$\frac{ - 6x + 18}{x(x - 3)( x + 3)}$

$\frac{ - 6(x - 3)}{x(x - 3)(x + 3)}$

$\frac{ - 6}{x(x + 3)}$

$- \frac{6}{ {x}^{2} + 3x }$
