{-8;0;2}
Объяснение:
m неравно -8; m неравно 0; m неравно 2
m(m+8)-(12m-4)/m+8 : 4m(m+8)-40m/m+8 = m-2/4m
m^2+8m-12m+4/m+8 : 4m^2+32-40m/m+8 = m-2/4m
m^2-4m+4/m+8 : 4m^2-8m/m+8 = m-2/4m
(m-2)^2/m+8 * m+8/4m^2-8m = m-2/4m
(m-2)^2 * 1/4m(m-2) = m-2/4m
(m-2) * 1/4m = m-2/4m
m-2/4m=m-2/4m
Утверждение верно для любого значения m
