You can put this solution on YOUR website!
i think p(x)=\"X%5E3+%2B+5+x%5E2+%2B8x+%2B40+\"
\n" ); document.write( "then
\n" ); document.write( "x=-5 is a root\r
\n" ); document.write( "\n" ); document.write( " 1 5 8 40
\n" ); document.write( "-5 -5 0 -40
\n" ); document.write( " 1 0 8 0\r
\n" ); document.write( "\n" ); document.write( "then \"P%28x%29=%28x%2B5%29%28x%5E2%2B8%29\"\r
\n" ); document.write( "\n" ); document.write( "
