a) A(x) = x¹⁷ - 12x¹⁶ + 12x¹⁵ - 12x¹⁶ +...+ 12x - 1 tại x = 11

b) Cho x - y = 5 *Tính B = 6x - 6y + 10 - 3ax + 3ay + 15a

c) Cho x - 2y = 6 *Tính C = \(\frac{x-y}{x+6}\) x−yx+6 (x ≠y và x≠-6)

d) Cho x,y,z ≠0 và x - y - z = 0 . Tính GT của BT sau:

D = (1 - \(\frac{z}{x}\) ) . ( 1 - \(\frac{y}{x}\)) . (1 + \(\frac{y}{z}\) )
