Jawaban pd lampiran

Hasil bagi = H(x)/4

4x + 1 = 0
4x = -1
x = - 1/4

-1/4 | 4.........-3........-7..........-2.......1
........|............-1...........1...........6/4...1/8
...........4.......-4.........-6.........-1/2....9/8

hasil = 1/4 ×(4x^3 - 4x^2 - 6x - 1/2) sisa 9/8
hasil = x^3 - x^2 - 6/4 x - 1/8 sisa 9/8
hasil = x^3 - x^2 - 3/2 x - 1/8 sisa 9/8
