(7-z/z-5) - (7z-8/5-z)
\n" ); document.write( "----
\n" ); document.write( "Re-write:
\n" ); document.write( "(7-z/z-5) + (7z-8/z-5)
\n" ); document.write( "---
\n" ); document.write( "Now the denomiators are the same:
\n" ); document.write( "---
\n" ); document.write( "= [7-z+7z-8]/(z-5)
\n" ); document.write( "---
\n" ); document.write( "= [6z-1]/[z-5]
