Good job

X^3+X=10 X=2 X=-1-2i X=-1+2i

[@PhilCoolMath]

Good 👍

How did x-2 became 1

[@mouradbelkas598]

Why complicate life X^3 + X = 10, X (X^2 + 1) = 10, since 10 is 1 x 10 and 2 x 5, therefore x = 2 and x^2 + 1 = 5, x =2. Easy and simple

[@Checkyourself.Physics.Math-GB]

But you missed two other solutions!

[@mouradbelkas598]

Your X2 and X3 are not solution since they can never produce 10 in the equation.

X=0+2, really ?
