Bonjour pouvez vous m'aider s'il vous plait ?

IL FAUT FACTORISER LES EXPRESSIONS SUIVANTES

A = 4a - 4m
B= 25 b2 - 15b + 10
C = C2 - 4c
D = = -4p2 - 12p
E = ( x + 2 ) (x - 6) + (x + 3) (x + 2)
F = (7i + 4)2 + (7 i + 4) (3i - 2 )
G = (2i - 7) + (2i - 7) (3i - 2)
H = (4x + 2) (x - 6) - (4x + 2) (2x - 3)
I = (7i - 2)2 - (7i - 2) (3i - 2) - (7i - 2)

JE SUIS EN 3°

MERCI

Bonjour,

A = 4a - 4m
A = 4 (a - m)

B= 25 b² - 15b + 10
B = 5 (5b² - 3b + 2)

C = C² - 4c
C = c (c - 4)

D =  -4p² - 12p
D = - 4p (p + 3)

E = ( x + 2 ) (x - 6) + (x + 3) (x + 2)
E = (x + 2) (x - 6 + x + 3)
E = (x + 2) (2x - 3)

F = (7i + 4)² + (7 i + 4) (3i - 2 )
F = (7i + 4) (7i + 4 + 3i - 2)
F = (7i + 4) (10i + 2)
