If it's not what You are looking for type in the equation solver your own equation and let us solve it.
(1/x+2)+(1/x^2-2x)-(8/x3-4x)=0
Domain of the equation: x+2)!=0
x∈R
Domain of the equation: x^2-2x)!=0
x∈R
Domain of the equation: x3-4x)!=0We add all the numbers together, and all the variables
x∈R
(1/x+2)+(1/x^2-2x)-(-4x+8/x3)=0
We get rid of parentheses
1/x+1/x^2-2x+4x-8/x3+2=0
We calculate fractions
We do not support expression: x^6
