Explicación paso a paso:

x/x+1+2x/x-1=15/4

x/x+1+2x/x-1=15/4(x^2-x+2x^2+2x)/(x^2-1)=15/4

x/x+1+2x/x-1=15/4(x^2-x+2x^2+2x)/(x^2-1)=15/44(3x^2+×)=15(x^2-1)

x/x+1+2x/x-1=15/4(x^2-x+2x^2+2x)/(x^2-1)=15/44(3x^2+×)=15(x^2-1)3x^2-4×-15=0

x/x+1+2x/x-1=15/4(x^2-x+2x^2+2x)/(x^2-1)=15/44(3x^2+×)=15(x^2-1)3x^2-4×-15=03x 5

x/x+1+2x/x-1=15/4(x^2-x+2x^2+2x)/(x^2-1)=15/44(3x^2+×)=15(x^2-1)3x^2-4×-15=03x 5x -3

x/x+1+2x/x-1=15/4(x^2-x+2x^2+2x)/(x^2-1)=15/44(3x^2+×)=15(x^2-1)3x^2-4×-15=03x 5x -3(3x+5)(x-3)=0

x/x+1+2x/x-1=15/4(x^2-x+2x^2+2x)/(x^2-1)=15/44(3x^2+×)=15(x^2-1)3x^2-4×-15=03x 5x -3(3x+5)(x-3)=03x+5=0-->x=-5/3

x/x+1+2x/x-1=15/4(x^2-x+2x^2+2x)/(x^2-1)=15/44(3x^2+×)=15(x^2-1)3x^2-4×-15=03x 5x -3(3x+5)(x-3)=03x+5=0-->x=-5/3x-3=0-->x=3

x/x+1+2x/x-1=15/4(x^2-x+2x^2+2x)/(x^2-1)=15/44(3x^2+×)=15(x^2-1)3x^2-4×-15=03x 5x -3(3x+5)(x-3)=03x+5=0-->x=-5/3x-3=0-->x=3x=3 ó x=-5/3
