You can put this solution on YOUR website!
It cannot be factored over the real numbers, but if you include complex numbers in the mix, then you can factor \"x%5E2+%2By%5E2\"\r

\n" ); document.write( "\n" ); document.write( "In this case, \"x%5E2+%2By%5E2\" factors to \"%28x%2Byi%29%28x-yi%29\". This is almost identical to the difference of squares but with an added \"i\" term.\r

\n" ); document.write( "\n" ); document.write( "If you have never heard of complex numbers or the \"i\" term, then the answer is you cannot factor \"x%5E2+%2By%5E2\".
