Jawapan:
# a = 19/7, p = 75/7, q = 25/7 #
Penjelasan:
Memanggil
# f_1 (x) = ax ^ 3-3x ^ 2 + 2x-3 #
# f_2 (x) = ax ^ 2-5x + a #
kami tahu itu
# f_1 (x) = q_1 (x) (x-2) + p # dan
# f_2 (x) = q_2 (x) (x-2) + q #
jadi
# f_1 (2) = 8a-12 + 4-3 = p #
# f_2 (2) = 4a-10 + a = q # dan juga
# p = 3q #
Menyelesaikan
# {(8a-11 = p), (5a-10 = q), (p = 3q):} #
kami memperolehi
# a = 19/7, p = 75/7, q = 25/7 #
