3/x+1-1/x-1=3x/x2-1
We move all terms to the left:
3/x+1-1/x-1-(3x/x2-1)=0
Domain of the equation: x!=0
x∈R
Domain of the equation: x2-1)!=0We add all the numbers together, and all the variables
x∈R
3/x-1/x-(3x/x2-1)=0
We get rid of parentheses
3/x-1/x-3x/x2+1=0
We calculate fractions
We do not support expression: x^3
