You can put this solution on YOUR website!
If you mean
\n" ); document.write( "x^2+2x-15 Then you need to reverse FOIL\r
\n" ); document.write( "\n" ); document.write( "( )( )
\n" ); document.write( "(x )(x ) Will give you x^2
\n" ); document.write( "(x+5 )(x-3 ) WIll give you x^2+2x-15\r
\n" ); document.write( "\n" ); document.write( "When using reverse FOIL remember: What times what will give me -15 but added together will give me 2.
\n" ); document.write( "
\n" );
