Solution for (n+2)/(n-8)-(n-6)/(n+4) equation: 


D( n )

n-8 = 0

n+4 = 0

n-8 = 0

n-8 = 0

n-8 = 0 // + 8

n = 8

n+4 = 0

n+4 = 0

n+4 = 0 // - 4

n = -4

n in (-oo:-4) U (-4:8) U (8:+oo)

(n+2)/(n-8)-((n-6)/(n+4)) = 0

(n+2)/(n-8)+(-1*(n-6))/(n+4) = 0

((n+2)*(n+4))/((n-8)*(n+4))+(-1*(n-6)*(n-8))/((n-8)*(n+4)) = 0

(n+2)*(n+4)-1*(n-6)*(n-8) = 0

20*n-40 = 0

(20*n-40)/((n-8)*(n+4)) = 0

(20*n-40)/((n-8)*(n+4)) = 0 // * (n-8)*(n+4)

20*n-40 = 0

20*n-40 = 0 // + 40

20*n = 40 // : 20

n = 40/20

n = 2

n = 2
