Question 169930
Solve for x: (4/x^2-1)=(2/x-1)-(3/x+1)
----------------------
(4/x^2-1)=(2/x-1)-(3/x+1)  Is it (2/x)+1, or 2/(x+1)?
I'll assume the latter.
4/(x^2-1) = 2/(x-1) - 3/(x+1)
{{{4/((x-1)*(x+1)) = 2/(x-1) - 3/(x+1)}}}
Multiply by (x-1)*(x+1)
4 = 2(x+1) - 3(x-1)
4 = 2x+2 - 3x+3
4 = 5x +5
5x = -1
x = -1/5
