You can put this solution on YOUR website!
You can factor a negative one from 1-3m to get -1(-1+3m) which rearranges to -1(3m-1).\r

\n" ); document.write( "\n" ); document.write( "This means that the sign in the second fraction will change from a negative to a positive.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"5%2F%283m-1%29-2%2F%281-3m%29\"$ will become $\"5%2F%283m-1%29%2B2%2F%283m-1%29\"$ \r
