Factor:
\n" ); document.write( "10) \"144x%5E2-900y%5E2\" Notice that this is a difference of squares:
\n" ); document.write( "\"%2812x%29%5E2-%2830y%29%5E2\" and this can be factored thus:
\n" ); document.write( "\"A%5E2-B%5E2+=+%28A-B%29%28A%2BB%29\" so...
\n" ); document.write( "\"144x%5E2-900y%5E2+=+highlight%28%2812x-30y%29%2812x%2B30y%29%29\"
\n" ); document.write( "11) \"54x%5E3-72x%5E2y%2B24xy%5E2\" First factor 6x.
\n" ); document.write( "\"6x%289x%5E2-12xy%2B4y%5E2%29\" Now factor the trinomial.
\n" ); document.write( "\"highlight%286x%283x-2y%29%283x-2y%29%29\"
\n" ); document.write( "
\n" );
