Solve for d:
\n" ); document.write( "\"sqrt%28d-12%29+=+sqrt%28d%29-2\" Square both sides.
\n" ); document.write( "\"d-12+=+d-4sqrt%28d%29%2B4\" Subtract d from both sides.
\n" ); document.write( "\"-12+=+-4sqrt%28d%29%2B4\" Subtract 4 from both sides.
\n" ); document.write( "\"-16+=+-4sqrt%28d%29\" Divide both sides by -4
\n" ); document.write( "\"4+=+sqrt%28d%29\" Finally, square both sides.
\n" ); document.write( "\"16+=+d\"
