document.write( "Hi,
\n" );
document.write( "2x³+6x²-20x= 2x (x²+3x-10)= 2x(x+5)(x-2)
\n" );
document.write( "2x(x+5)(x-2)=0 
\n" );
document.write( "  2x = 0   x = 0
\n" );
document.write( "0r (x+5)= 0   x = -5
\n" );
document.write( "0r (x-2)=0    x = 2 
\n" );
document.write( "solution set {-5, 0, 2} is correct.  Good work! \n" );
document.write( "

\n" );
