x/x+4 + x+2/x-4 = 32/x^2 - 16
x/x+4 + x+2/x-4 = 32/ (x-4)(x+4) | (x-4)(x+4) не равно 0 x не равен +- 4
x(x-4) + (x+2)(x+4) = 32
x^2 - 4x + x^2 + 4x + 2x + 8 = 32
2x^2 + 2x - 24 = 0 | : 2
x^2 + x - 12 = 0
D = 1 - 4* (-12) = 1 + 48 = 49 корень из D = 7
x1 = - 1 + 7/ 2 = 3
x2 = - 1 - 7/ 2 = - 4
ответ : -4, 3
