You can put this solution on YOUR website!
2 + squareroot(2-x) = x
\n" ); document.write( "------------------
\n" ); document.write( "Step 1 - isolate the radical.
\n" ); document.write( "\"sqrt%282-x%29+=+x-2\"
\n" ); document.write( "Then square both sides. This eliminates the radical.
\n" ); document.write( "\"%282-x%29+=+x%5E2+-+4x+%2B+4\"
\n" ); document.write( "\"x%5E2+-+3x+%2B+2+=+0\"
\n" ); document.write( "(x-1)*(x-2) = 0
\n" ); document.write( "x = 1
\n" ); document.write( "x = 2
\n" ); document.write( "----------
\n" ); document.write( "2 works.
\n" ); document.write( "The 1 is an extraneous solution, ignore it.
\n" ); document.write( "
\n" );
