Solve:
\n" ); document.write( " $\"-3u+=+u%5E2\"$ Expand the right side.
\n" ); document.write( " $\"-3u+=+u%2Au\"$ Now divide both sides by u.
\n" ); document.write( " $\"-3u%2Fu+=+u%2Au%2Fu\"$ Now you can see that you can cancel the u's on both sides to get:
\n" ); document.write( " $\"-3+=+u\"$
\n" ); document.write( "Check:
\n" ); document.write( " $\"-3u+=+u%5E2\"$ Substitute $\"u+=+-3\"$
\n" ); document.write( " $\"%28-3%29%28-3%29+=+%28-3%29%5E2\"$
\n" ); document.write( " $\"9+=+9\"$ OK! \n" ); document.write( "

\n" );
