10/x-1+1=20/x^2-1
We move all terms to the left:
10/x-1+1-(20/x^2-1)=0
Domain of the equation: x!=0
x∈R
Domain of the equation: x^2-1)!=0We add all the numbers together, and all the variables
x∈R
10/x-(20/x^2-1)=0
We get rid of parentheses
10/x-20/x^2+1=0
We calculate fractions
We do not support expression: x^3
