\n" ); document.write( " $\"%28%28r-2%29%28r-2%29%29%2F%282-r%29%282%2Br%29\"$ Rearrange the denominator.
\n" ); document.write( " $\"%28cross%28%28r-2%29%29%28r-2%29%29%2F%28-cross%28%28r-2%29%29%28r%2B2%29%29\"$ Cancel the indicated terms.
\n" ); document.write( " $\"-%28%28r-2%29%2F%28r%2B2%29%29\"$ \n" ); document.write( "
