I) Développer puis réduire : A = 8 (x – 3)

B = 5 (2 x − 6)

C = 3 (5 x – 4)

D = 6 (3 x + 9)

E = 2 (4 x + 4 y − 3)

F = 3 x (2 x − 7)

G = 4 (2 x + 5) + 3 (x − 6)

H = 2 (3 x + 4 y – 2)

I = 2 x (x + 1) + x (5 x − 2)

J = 2 (3 x + 5) + 4 (2 x + 3)

K = 3 (2 x + 5) + 2 (4 x + 3)

L = 4 (2 x + 7) + 3 (x − 6)

M = 5 (3 x + 4) + 6 (2 x − 3)

N = (x – y) × x

O = 2 (4 a + 2 b) + 3 (6 a – b) + a (2 + b)

P = 4 (2 x + 3 y + 4) + 3 (5 x + 2 y − 5)

Q = 3 x (5 x + 3) + 6 x² + 2

I) Factoriser :

A = 6 a – 3

B = 4 – 4 x

C = 9 a + 5 a2

D = a × b – 13 a

E = 2 a × 3 x + 4 × 2 a

F = 4 a2 – a b

G = x × 3 b + x × c

H = 3 a b + 3 a c

I = 6 a b + 2 a c

J = 2 a + 7 a × 2 b – 3 a2 × 2
