If it's not what You are looking for type in the equation solver your own equation and let us solve it.
(-x^2+1)/x+2x^2+1=0
Domain of the equation: x!=0We add all the numbers together, and all the variables
x∈R
2x^2+(-x^2+1)/x+1=0
We multiply all the terms by the denominator
(-x^2+1)+2x^2*x+1*x=0
We add all the numbers together, and all the variables
(-x^2+1)+2x^2*x+x=0
Wy multiply elements
(-x^2+1)+2x^3+x=0
We get rid of parentheses
-x^2+2x^3+x+1=0
We do not support expression: x^3
