@Angel.
You are correct upto what you have done but that's not the final answer.
We have to calculate uvl form reaction B to x then substrate from your answer and then you will get the final answer.

Bending moment is max where Shear Force is zero.
Total load = 1/2 W l.
Rb =reaction at B, total Moment at A = 0.
Rb* l= 1/2 Wl * l/3.
Rb= Wl/6.
Shear force at a dist x from B=0.
Wl/6- Wx/l*1/2*x=0.
X = l/√3.
Bending moment is max at this point from B.
Rb *x= wl^2/6√3.
