\n" ); document.write( ":
\n" ); document.write( "Note that you can factor the numerator and the denominator is the difference of squares, you can factor also, then cancel out (r-2)
\n" ); document.write( " $\"%28%28r-3%29%28r-2%29%29%2F%28%28r%2B2%29%28r-2%29%29\"$ = $\"%28r-3%29%2F%28r%2B2%29\"$ \n" ); document.write( "
