Question

Помогите!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

$( \frac{5}{x - 2} - x - 2) \times \frac{2 - x}{ {x}^{2} + 6x + 9 } = (\frac{5}{x - 2} -(x + 2)) \times \frac{2 - x}{ {x}^{2} + 6x + 9} = ( \frac{5}{x - 2} - \frac{(x + 2)(x - 2)}{x - 2} ) \times \frac{2 - x}{ {x}^{2} + 6x + 9 } = \frac{5 - ( {x}^{2} - 4) }{x - 2} \times \frac{2 - x}{ {x}^{2} + 6x + 9} = \frac{5 - {x}^{2} + 9}{x - 2} \times \frac{2 - x}{ {x}^{2} + 6x + 9} = \frac{ 9 - {x}^{2} }{ - (2 - x)} \times \frac{2 - x}{ {(x + 3)}^{2} } = \frac{(3 - x)(3 + x)}{ - {(x + 3)}^{2} } = - \frac{3 - x}{x + 3} = \frac{x - 3}{x + 3}$
