You can put this solution on YOUR website!
Just looking at the equation, I see that 0 works for a solution.
\n" ); document.write( " $\"0%5E2+=+0\"$
\n" ); document.write( "I see that +1 works
\n" ); document.write( " $\"1%5E2+=+1\"$
\n" ); document.write( "I see that -1 doesn't work
\n" ); document.write( "(-1)^2 =? -1 no
\n" ); document.write( "Now the equation:
\n" ); document.write( " $\"x%5E2+=+x\"$
\n" ); document.write( " $\"x%5E2+-+x+=+0\"$
\n" ); document.write( " $\"x+%2A+%28x+-+1%29+=+0\"$
\n" ); document.write( "x = 0
\n" ); document.write( "x = +1
\n" ); document.write( "so, I was right
\n" ); document.write( " \n" ); document.write( "

\n" );
