Currently doing my economics dissertation and I have a reallllly long formula (essentially expanded squares, for the purpose of completeness in deriving a model), and I'm having trouble formatting it. Essentially I have a really long bracket that needs to be "newline"ed but it doesn't seem to like it doing it in the middle of a bracket. If you copy the code into Math you'll see what I mean (?s all over the shop)! I've tried all sorts of positions of { }s but to no avail. It really doesn't like me interrupting a (.....). Any help greatly appreciated!

Formula:

E^CB L=1 over 2 %lambda E ({%alpha^2%DELTA m^2} + {%alpha^2 v^2} +{%alpha^2{%pi^e}^2}+{e^2}+{k^2} +{2%alpha^2%DELTA mv} + {2%alpha^2%DELTA m%pi^e} + {2%alpha%DELTA me} - {2%alpha%DELTA mk} newline alignl - {2%alpha^2 v%pi^e} + {2%alpha ve} - {2%alpha vk} -{2%alpha%pi^e e }+ {2%alpha%pi^e k -2ek}) + 1 over 2(%DELTA m^2 + v^2 +2%DELTA mv)
