x^3+x^2-20x=0
\n" ); document.write( "Start by factoring out what is common among all three terms:
\n" ); document.write( "x(x^2+x-20) = 0
\n" ); document.write( "Factor the expression inside the parenthesis:
\n" ); document.write( "x(x+5)(x-4) = 0
\n" ); document.write( ".
\n" ); document.write( "Set each term to zero, giving you:
\n" ); document.write( "x = (-5, 0, 4}
\n" ); document.write( "
\n" ); document.write( "
