Bonjour
Factoriser :
A = 9 x² - 5 x
A = x (9x - 5)
B= 6x + 9
B = 3 (2x + 3)
C = x (x + 5)+ x (3 x - 2)
C = x (x + 5 + 3x - 2)
C = x (4x + 3)
D = (x + 4) (x - 6) + (- 1 + x) (x - 6)
D = (x - 6) (x + 4 - 1 + x)
D = (x - 6) (2x + 3)
E= (3 x - 1)-(3 x - 1)²
E = - (3x - 2) (3x - 1)
G = 4 - X²
G = - (x - 2) (x + 2)
I= 25 - 36a²
I = - (6a - 5) (- 6a + 5)
J=(4 x - 3)² - 1
J = (4x - 3 - 1) (4x - 3 + 1)
J = (4x - 4) (4x - 2)
