\n" ); document.write( "Alright ..... I get a very long and invoved answer here, which is not yours or the one the book gives.
\n" ); document.write( "First, let's work a simpler problem to see how I got this.
\n" ); document.write( "\"+%28-a%2Bb%29%28c-d%2Be%29+\"
\n" ); document.write( "We multiply this out ...
\n" ); document.write( "\"+%28-ac+%2B+ad+-ae%29+%2B+%28+bc+-bd+%2B+be%29+\"
\n" ); document.write( "Now ... lets apply this same process to the two quantities.
\n" ); document.write( "\"+-+3x%5E5+%2B+24x%5E4y+-+48x%5E3y%5E2+%2B+x%5E2y+-+8xy%5E2+%2B+16y%5E3+\"
\n" ); document.write( "There are no like terms. THIS IS your answer.
