How to solve the equation 2 / x = x ^ 2 + 2x; X ^ 2 is the square of X How to solve the equation 2 / x = x ^ 2 + 2x; X ^ 2 is the square of X

How to solve the equation 2 / x = x ^ 2 + 2x; X ^ 2 is the square of X How to solve the equation 2 / x = x ^ 2 + 2x; X ^ 2 is the square of X

After simplification, a cubic equation is obtained
X³+2X²-2=0
You can use the root formula of cubic equation of one variable (but it's very complicated)
Maybe there are other ways to solve it
By the way: the first step of the one above is wrong^-^
