You can put this solution on YOUR website!
x^2+4x+2=0
\n" ); document.write( "a=1, b=4, c=2
\n" ); document.write( "x=[-4+-sqrt(4^2-4*2]/2\r
\n" ); document.write( "\n" ); document.write( "x=[-4+-sqrt8]/2\r
\n" ); document.write( "\n" ); document.write( "x=[-4+-2sqrt2]/2
\n" ); document.write( "Dividing by \"2\" you get:\r
\n" ); document.write( "\n" ); document.write( "x=[-2+-sqrt2]
