Answer 1

Ответ:

$\frac{x^2-4}{16} *(\frac{x+2}{x-2} -\frac{x-2}{x+2} ) =\\\frac{(x-2)(x+2)}{16} *\frac{(x+2)^2-(x-2)^2}{(x-2)(x+2)} =\\\frac{1}{16} *4*2x=\\\frac{1}{16} *8x= \\\frac{1}{2} x=\\\frac{1}{2} *(-10)=\\-5$

Answer 2

Ответ:

-5

Пошаговое объяснение:

(х²-4)/16 * ( (х+2)/(х-2) - (х-2)/(х+2) ) =

( (х-2)*(х+2) )/16 * ( (х+2)² - (х-2)² )/( (х-2)*(х+2) ) =

( (х-2)*(х+2) )/16 * (4 * 2х)/( (х-2)*(х+2) ) =

(х + 2)/16 * (4 * 2х)/(х + 2) =

1/16 * 4 * 2х =

1/16 * 8х = 8/16х = 1/2х

х = -10

1/2х = 1/2 * (-10) = -10/2 = -5
