You can put this solution on YOUR website!
Okay, instead of making a long list of the nine items, we will do it vertically...so we get (ignore the spacing lines...they're there to line stuff up)
\n" ); document.write( "(a^2 + 3ab - b^2)(a^2 - 5ab + b^2) =
\n" ); document.write( "a^4 - 5a^3b + a^2b^2
\n" ); document.write( "____+ 3a^3b - 15a^2b^2 + 3ab^3
\n" ); document.write( "____________- a^2b^2 + 5ab^3 - b^4 =
\n" ); document.write( "a^4 - 2a^3b - 15a^2b^2 + 8ab^3 - b^4
\n" ); document.write( "
\n" );
