Solution for (2x)/(x+15)+(x+15)/(x-15)=0 equation: 


D( x )

x-15 = 0

x+15 = 0

x-15 = 0

x-15 = 0

x-15 = 0 // + 15

x = 15

x+15 = 0

x+15 = 0

x+15 = 0 // - 15

x = -15

x in (-oo:-15) U (-15:15) U (15:+oo)

(2*x)/(x+15)+(x+15)/(x-15) = 0

(2*x*(x-15))/((x+15)*(x-15))+((x+15)^2)/((x+15)*(x-15)) = 0

2*x*(x-15)+(x+15)^2 = 0

3*x^2+225 = 0

(3*x^2+225)/((x+15)*(x-15)) = 0

(3*x^2+225)/((x+15)*(x-15)) = 0 // * (x+15)*(x-15)

3*x^2+225 = 0

3*x^2 = -225 // : 3

x^2 = -75

x belongs to the empty set
