(x+2)(x-3)(x+4)
\n" ); document.write( ".
\n" ); document.write( "use FOIL first
\n" ); document.write( ".
\n" ); document.write( "(x+2) ( x^2 +4x -3x -12)
\n" ); document.write( ".
\n" ); document.write( "(x+2) ( x^2 + 1x -12)
\n" ); document.write( ".
\n" ); document.write( "now use distribution
\n" ); document.write( ".
\n" ); document.write( "x(x^2 +x -12) +2 ( x^2 +x -12)
\n" ); document.write( ".
\n" ); document.write( "x^3 +x^2 -12x +2x^2 +2x -24
\n" ); document.write( ".
\n" ); document.write( "x^3 +3x^2 -10x -24
\n" ); document.write( ".
\n" ); document.write( "checking,,,if x=0,,, original and answer = -24,,ok
\n" ); document.write( "if x=1,,,both = -30,,,ok
\n" ); document.write( " \n" ); document.write( "
\n" );
