1) p(x) = x⁴ - 2x² - 5 di bagi (2x+1)
..........1......0.....-2.......0 ....-5
-1/2..........-1/2..1/4.....7/8..-7/16
----------------------------------------
..........1...-1/2...-7/4....7/8..-87/16
hasil bagi = x³-1/2 x² - 7/4 x + 7/8
sisa = -87/16
2) f(x) = 2x³ - x² + 3x - 9 dibagi (2x+1)
..........2......-1......3......-9
-1/2............-1......1.......-2
---------------------------------
..........2......-2......4.......-11
hasil bagi = x² - x + 2
sisa = -11
