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
