Vastaus:
# A = 19/7, s = 75/7, q = 25/7 #
Selitys:
Kutsumus
# F_1 (x) = ax ^ 3-3x ^ 2 + 2x-3 #
# F_2 (x) = ax ^ 2-5x + a #
tiedämme sen
# F_1 (x) = q_1 (x) (x-2) + p # ja
# F_2 (x) = q_2 (x) (x-2) + q #
niin
# f_1 (2) = 8a-12 + 4-3 = p #
# F_2 (2) = 4a-10 + a = q # ja myös
# P = 3Q #
Ongelmien
# {(8a-11 = p), (5a-10 = q), (p = 3q):} #
saamme
# A = 19/7, s = 75/7, q = 25/7 #
