You can put this solution on YOUR website!
x(x-3)=x
\n" ); document.write( "----------------
\n" ); document.write( "Divide by x
\n" ); document.write( "x-3 = 1
\n" ); document.write( "x = 4
\n" ); document.write( "That's one answer, but it overlooks another possibility, that x = 0.
\n" ); document.write( "To get both:
\n" ); document.write( "x^2-3x = x
\n" ); document.write( "x^2 -4x = 0
\n" ); document.write( "x(x-4) = 0
\n" ); document.write( "Now it's more obvious that x = 0 and x = 4. \n" ); document.write( "

\n" );
