Question

Помогите!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

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