Explicación paso a paso:

[6/(x+4) + 2/(x^2+2x-8)] [6/(x+4) / 2/(x^2+2x-8)]=

[6/(x+4) + 2/(x+4)(x-2)] [6/(x+4) / 2/(x+4)(x-2)]=

[6(x-2)/(x+4)(x-2) + 2/(x+4)(x-2)] [6/(x+4) * (x+4)(x-2)/2]=

[6x-12/(x+4)(x-2) + 2/(x+4)(x-2)] [3 * (x-2)]=

[6x-10/(x+4)(x-2)] [3x-6]=

[2(3x-5)/(x+4)(x-2)] [3(x-2)]=

[2(3x-5)/(x+4)] [3]=

[(6x-10)/(x+4)] [3]=

18x-30/x+4=
