Use synthetic division to verify the upper bound and lower bound of the zeros of f.
\n" ); document.write( "f(x) = 2x^4 -8x +3
\n" ); document.write( "Upper bound: x= 3; Lower bound: x= -4
\n" ); document.write( "---------------
\n" ); document.write( "3)....2....0....0....-8....3
\n" ); document.write( ".......2.....6...18....46....|..141
\n" ); document.write( "---
\n" ); document.write( "So f(3) = 141
\n" ); document.write( "-----
\n" ); document.write( "-4)....2....0....0....-8....3
\n" ); document.write( "........2....-8....32....-136....|..547
\n" ); document.write( "---
\n" ); document.write( "So f(-4) = 547
\n" ); document.write( "=================
