how to simplify this equation



I have below equation
------------------
%e^(-sqrt(sqrt(73)-10)*%psi-sqrt(-sqrt(73)-10)*%psi)*((7*sqrt(73)+73)*f_6_1(0)*%e^(2*sqrt(sqrt(73)-10)*%psi+sqrt(-sqrt(73)-10)*%psi)+((73-7*sqrt(73))*f_6_1(0)*%e^(2*sqrt(-sqrt(73)-10)*%psi)+(73-7*sqrt(73))*f_6_1(0))*%e^(sqrt(sqrt(73)-10)*%psi)+(7*sqrt(73)+73)*f_6_1(0)*%e^(sqrt(-sqrt(73)-10)*%psi))/292;
-------------
and I want to simplify the equation so that it become (longEquation) x
f_6_1(0)

can anyone give me some hint on how to do it?it seems fullratsimp, tragsimp
can't help me to do it..

thanks in advanced
