You can put this solution on YOUR website!
\"x%5E2%2B49\"....write \"49\" as \"7%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2%2B7%5E2\"...here we have the sum of squares; usually when you factor, you are looking for real factors, but if you allow
\n" ); document.write( "complex factors then you can always factor \"A%5E2%2BB%5E2\" like this:\r
\n" ); document.write( "\n" ); document.write( "\"A%5E2%2BB%5E2+=+A%5E2-%28-1%2AB%5E2%29+=+A%5E2-%28iB%29%5E2+=+%28A%2BiB%29+%28A-iB%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, you will have \r
\n" ); document.write( "\n" ); document.write( "\"x%5E2-%287i%29%5E2\" which is\r
\n" ); document.write( "\n" ); document.write( "\"%28x-7i%29%28x%2B7i%29\"
\n" ); document.write( "
\n" );
