Question #2cb93

Answer 1

`x=-1`

Explanation:

`1/2+1/3+1/6 = (-1)^2 = 1`

This is a transcendental equation.
One can only guess or solve it with successive approximations like the Newton-Raphson method.
It is clear in this equation though that x must be negative because for positive x, the LHS of the equation is much bigger than the RHS.
