You can put this solution on YOUR website!
$\"x%5E2-3=2x\"$ subtract 2x from both sides and re-arrange terms:
\n" ); document.write( " $\"x%5E2-2x-3=0\"$ a quadratic equation that factorises easily to:
\n" ); document.write( "(x+1)(x-3)=0
\n" ); document.write( "x+1=0
\n" ); document.write( "x=-1
\n" ); document.write( "x-3=0
\n" ); document.write( "x=3
