Can anybody help in writing the following formula… I am having trouble. LHS I can write, but not the RHS.

This is based on mafp's answer, but doesn't use aligned in the left. Note the \! in front of \begin{aligned} and the {}+, which are needed for proper spacing!
\documentclass[twocolumn]{article}
\usepackage[a4paper,margin=1cm]{geometry}
\usepackage{amsmath}
\begin{document}
\begin{enumerate}
\item The degree of (C) is 3.
\item The degree of (A) is 1.
\item%
$
\!\begin{aligned}[t]
-3x(x+1)-2x(x-1) \\
{}+4(x^2-3x-1) &= \!\begin{aligned}[t]
-3x^2-3x-2x^2+2x \\
{}+4x^2-12x-4
\end{aligned} \\
&= -x^2-13x-4
\end{aligned}
$
\end{enumerate}
\end{document}
I take it the main issue is the typesetting of the curly braces around the material immediately below "max". Just change
\max_{{P^{\circ}_t(j)}}
to
\max_{\{P^{\circ}_t(j)\}}
Remember that in order to typeset curly braces, you must type \{ and \}, not just { and }.
No need for the \limits directive, by the way.
To fully reproduce the equation shown in the screenshot, you also need to provide \mid t items in two of the subscripts.
\documentclass{article}
\begin{document}
\begin{equation}
\max_{\{P^{\circ}_t(j)\}} E_{t} \sum_{s=0}^{\infty} \zeta^s M_{t,t+s}
\left[ P^{\circ}_{t+s\mid t}(j) - \mathcal{MC}_{t+s}(j) \right] Y_{t+s\mid t}(j)
\end{equation}
\end{document}

You can use
\DeclareMathOperator*fromamsmathto declare an operator accepting "limits" in super/sub script positions:As egreg comments, perhaps one could use
\vcenterinstead of an explicit dimension in the definition of\MyS; in this way, the square will be vertically centered with respect to the equal sign:Notice also the use of
\mathbinin the definition of\Osqto have the proper spacing for a binary operator.
