\n" ); document.write( "\"%28x%2By%29%5E2\" is square of the sum and it is equal to \"x%5E2%2B2%26%238290%3Bxy%2By%5E2\" and it is a perfect square trinomial\r
\n" ); document.write( "\n" ); document.write( "and \"x%5E2%2By%5E2\" is the sum of the squares\r
\n" ); document.write( "\n" ); document.write( "why \"%28x%2By%29%5E2\" is not equal to \"x%5E2%2By%5E2\", : because it is a binomial and \"%28x%2By%29%5E2\" is \"2%26%238290%3Bxy\" greater then \"x%5E2%2By%5E2\"
