Add or subtract as indicated 7b+6/6b-36 - b+2/b-6
\n" ); document.write( ":
\n" ); document.write( " $\"%287b%2B6%29%2F%286b-36%29\"$ - $\"%28b%2B2%29%2F%28b-6%29\"$
\n" ); document.write( "Factor out 6 in 1st denominator, results:
\n" ); document.write( " $\"%287b%2B6%29%2F%286%28b-6%29%29\"$ - $\"%28b%2B2%29%2F%28b-6%29\"$
\n" ); document.write( "the common denominator is 6(b-6), therefore
\n" ); document.write( " $\"%28%287b%2B6%29-6%28b%2B2%29%29%2F6%28b-6%29\"$ = $\"%287b+%2B+6+-+6b+-+12%29%2F6%28b-6%29\"$
