You can put this solution on YOUR website!
(x/(x+7))^2 = 4( x)(x+7) - 4
\n" ); document.write( "---------------
\n" ); document.write( "Let w = x/(x+7)
\n" ); document.write( "----------
\n" ); document.write( "Rewrite to get:
\n" ); document.write( "w^2 - 4w - 4 = 0
\n" ); document.write( "---------
