You can put this solution on YOUR website!
Divide out x or -x.
\n" ); document.write( "12 is the last term, so sub ą 1, 2, 3 & 4 for x and see if the polynomial is zero.
\n" ); document.write( "If +1 makes it zero, then (x-1) is a factor, etc
\n" ); document.write( "---------
\n" ); document.write( "If you find a factor, divide by it, then you have a quadratic left.\r
