Answer 1

Ответ:

Объяснение:

x-6/x-2 + х+2/x-2 = x-6+x+2 / x-2 = 2x-4/x-2 - сумма дробей

x-6/x-2 - х+2/x-2 = x-6-x-2 / x-2 = -8/x-2 - разность дробей

Answer 2

$\displaystyle\bf\\1)\\\\\frac{x-6}{x-2} +\frac{x+2}{x-2} =\frac{x-6+x+2}{x-2}=\frac{2x-4}{x-2}=\frac{2\cdot(x-2)}{x-2} =2\\\\\\2)\\\\\frac{x-6}{x-2} -\frac{x+2}{x-2} =\frac{x-6-x-2}{x-2}=\frac{-8}{x-2}=-\frac{8}{x-2}$
