Question

помогите, пожалуста!!!​

Answer 1

Ответ:

$-\frac{14m}{(m+2)(m-2)^2}$

Объяснение:

$\frac{2}{m+2} +\frac{m+3}{m^2-4} -\frac{3m+1}{m^2-4m+4} \\\\\frac{2}{m+2} +\frac{m+3}{(m-2)(m+2)} -\frac{3m+1}{(m-2)^2} \\\\\frac{2(m-2)^2+(m-2)(m+3)-(m+2)(3m+1)}{(m+2)(m-2)^2} \\\\\frac{2(m-2)^2+m^2+3m-2m-6-(3m^2+7m+2)}{(m+2)(m-2)^2} \\\\\frac{2(m-2)^2+m^2+3m-2m-6-3m^2-7m-2}{(m+2)(m-2)^2} \\\\\frac{2(m^2-4m+4)-2m^2-6m-8}{(m+2)(m-2)^2} \\\\\frac{2m^2-8m+8-2m^2-6m-8}{(m+2)(m-2)^2}\\\\-\frac{14m}{(m+2)(m-2)^2}$
