ed84c Posted January 27, 2005 Share Posted January 27, 2005 Im having difficulty cancelling down the following; (n+(W-1) * n+(Gw*(L-1))) – (n* n+(GW *(L-1))+(W-1)) anybody got any ideas? Link to comment Share on other sites More sharing options...
Deified Posted January 27, 2005 Share Posted January 27, 2005 n+nw-n+gwl-gw-n(squared)+gwl-gw+w-1 nw+2gwl-2gw-n^2+w-1 Not sure if there are any tricks here, but thats my best guess. Link to comment Share on other sites More sharing options...

NSX Posted January 29, 2005 Share Posted January 29, 2005 What do you mean by cancelling it down? Link to comment Share on other sites More sharing options...
jordan Posted January 29, 2005 Share Posted January 29, 2005 n+nw-n+gwl-gw-n(squared)+gwl-gw+w-1nw+2gwl-2gw-n^2+w-1 You forgot to carry the subraction sign all the way through. If should be: n+nw-n+gwl-gw-n(squared)-gwl+gw-w+1 and that boils down to: -n2+wn-w+1 I can't factor that any more unless n(w-n)+(1-w) helps.

Mart Posted January 29, 2005 Share Posted January 29, 2005 -n2+wn-w+1 Could go this way X = -n2+wn-w+1= w(n-1) + 1 - n2 and 1 - n2= (1-n)(1+n) therefore X = w(n-1) + (1-n)(1+n) = w(n-1) - (n-1)(1+n) = (n-1)(w-n-1) X = (n-1)(w-n-1) Check it. I may have made a mistake. Easy to do. Link to comment Share on other sites More sharing options...
