\begin{eqnarray}
\tag{A8}
2x+3y+4z+2u+7o+8k+90l+43+56+45p+33h \nonumber \\
&+& 89n+90m+34j+23a+45b+56f=0
\end{eqnarray}
But I am not getting the required equation with name A8. If anyone can figure it out you're most welcome.

Don't use eqnarray!
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
&\;2x+3y+4z+2u+7o+8k+90l+43+56+45p+33h\nonumber\\
+&\;89n+90m+34j+23a+45b+56f\tag{A8}
\end{align}
\end{document}
My recommended version
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{multline}
2x+3y+4z+2u+7o+8k+90l+43+56+45p+33h\\
+89n+90m+34j+23a+45b+56f\tag{A8}
\end{multline}
\end{document}
