We investigate the solvability of the matrix equation $AX^{2} = B$ in which the multiplication is the semi-tensor product. Then compatible conditions on the matrices $A$ and $B$ are established in each case and necessary and sufficient condition for the solvability is discussed. In addition, concrete methods of solving the equation are provided.
