factor the pollynomial completely
\n" ); document.write( "x3+5x2-8x-40
\n" ); document.write( "------------
\n" ); document.write( "In a classroom, these are always integers.
\n" ); document.write( "Look at the 40 - a zero will be a factor of 40.
\n" ); document.write( "Try (+ and minus) 1, 2, 4 and 5. f(-5) = 0, so (x+5) is a factor.
\n" ); document.write( "Once you divide by (x+5), it's only a 2nd order, easy to factor further, if possible.
\n" ); document.write( "--------------
\n" ); document.write( "Another approach is to graph the function and look for zeroes.
