You can put this solution on YOUR website!
$\"+sqrt%282y%2B1%29-19=0+\"$ ---> $\"+sqrt%282y%2B1%29=19\"$
\n" ); document.write( "Square both sides (keeping in mind that you risk adding extraneous solutions) to get
\n" ); document.write( " $\"2y%2B1=19%5E2\"$ --> $\"2y%2B1=361\"$ --> $\"2y=360\"$ --> $\"y=180\"$
\n" ); document.write( "At this point you verify to make sure that you did not add an extraneous solution, but it's OK. \n" ); document.write( "
