$\"2y%5E2+-+162+=+0\"$
\n" ); document.write( "I know how to solve it, but I'm not sure what the
\n" ); document.write( "\"factoring\" is about. I guess it means to factor out a $\"2\"$
\n" ); document.write( "from the left side like this:
\n" ); document.write( " $\"2%28y%5E2+-+81%29+=+0\"$
\n" ); document.write( "Now if I divide both sides by $\"2\"$ , I get
\n" ); document.write( " $\"y%5E2+-+81+=+0\"$ (since $\"0%2F2+=+0\"$ )
\n" ); document.write( " $\"y%5E2+=+81\"$
\n" ); document.write( "Take the square root of both sides
\n" ); document.write( " $\"y+=+9\"$
\n" ); document.write( "and
\n" ); document.write( " $\"y+=+-9\"$
\n" ); document.write( "I think you were half right \n" ); document.write( "
