You can put this solution on YOUR website!
this is particularly fun because of the huge number 8448
\n" ); document.write( "but you want factors of 8448 that differ by 8
\n" ); document.write( "that is one factor is 8 more than the other.
\n" ); document.write( "the larger number is is negative and the smaller one is positive.
\n" ); document.write( "the square root of 8448 is a bit more than 91 almost 92
\n" ); document.write( "what would happen if you tried 4 more with 4 less?
\n" ); document.write( "96 and 88 are 8 apart is their product 8448?
\n" ); document.write( "so the numbers are near that but the product must be 8448
\n" ); document.write( "that is the key to the whole problem\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
