Question

x/x+1 + 2x/x-1=15/4 si lo pueden explicar mejor :)

Answer 1

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

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

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

3x^2-4x-15=0

3x           5

 x           -3

(3x+5)(x-3)=0

3x+5=0-->x=-5/3

x-3=0-->x=3

x=3 ó x=-5/3

Answer 2

Hola

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

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

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

3x^2 - 4x - 15 = 0

3x _ 5

x _ -3

(3x+5) (x-3) = 0

3x + 5 = 0 x = -5/3

x - 3 = 0 x = 3

x = 3 o x = -5/3

Espero q te ayude, ten lindo dia

Cuidate.
