If it's not what You are looking for type in the equation solver your own equation and let us solve it.
(1/z^2)+(1/z)+2=0
Domain of the equation: z^2)!=0
z!=0/1
z!=0
z∈R
Domain of the equation: z)!=0We add all the numbers together, and all the variables
z!=0/1
z!=0
z∈R
(1/z^2)+(+1/z)+2=0
We get rid of parentheses
1/z^2+1/z+2=0
We calculate fractions
We do not support ezpression: z^3
