What are some simplified conditions for which:


$$W\bigg(A-\frac{X}{W}\bigg)^3\bigg[X-AW-\frac{AY}{N}(B+D)-\frac{AZ}{N}(C+D+E+F+G)\bigg]+\frac{X}{N}\bigg[Y(A+H)(B+D)+AZ(C+D+E+F+G)\bigg]<0$$


**WHERE:**


All of the letters are positive parameters (not constants) and:


$1.$ $$A,B,C,D,E,F,G,H < N \implies \frac{A}{N},\frac{B}{N},\frac{C}{N},\frac{D}{N},\f rac{E}{N},\frac{F}{N},\frac{G}{N},\frac{H}{N} <1 $$


$2.$ $AW>X$


Is this problem tractable by hand, or do I have to use Maple/Matlab to simplify my expression somehow?

Thanks.
