\n" ); document.write( "P(x) = 2x^4 - 7x^3 + 5x^2 - 7x + 3
\n" ); document.write( "1. lower between 0 & 1, upper between 2 and 4. real zeroes: x = .5, 3
\n" ); document.write( "Using synthetic Division:
\n" ); document.write( "3 2 -7 5 -7 3
\n" ); document.write( " 6 -3 6 -3
\n" ); document.write( " 2 -1 2 -1 0
\n" ); document.write( "0.5 1 0 1
\n" ); document.write( " 2 0 2 0
\n" ); document.write( "(x-3)(x-.5)(2x^2 + 2)
\n" ); document.write( "2. P(x) = 2(x-3)(x-.5)(x -i)(x+i)
