Объяснение:
1) 5/2-х -x^3-3/x-2 = 5/-(x-2) - x^3-3/x-2 = -5+x^3-3/x-2 = -2+x^3/x-2
2) 16-7x/(x-4)^2 - x-x^2/(4-x)^2 = 16-7x/(x-4)^2 - x-x^2/(-(x-4))^2 = 16-7x/(x-4)^2 - c-x^2/(x-4)^2 = 16-7x-(x-x^2)/(x-4)^2 = 16-7x-x+x^2/(x-4)^2 = 16-8x+x^2/(x-4)^2 = (4-x)^2/(x-4)^2 = (-(x-4))^2/(x-4)^2 = (x-4)^2/(x-4)^2 = 1
