Factoriser mes expressions suivantes: A= 2x au cube - 3x au carré + 6x B= 2x(x+1)+(x-2)(x+1) C= 4x au carré - 9 D= (2x+3) au carré -2x (2x+3) E= (5x-3) au carré

A= 2x^3 - 3x^2 + 6x
A= x (2x^2 - 3x + 6)

B= 2x(x+1) + (x-2)(x+1)
B= (x+1)(2x + x-2)
B= (x+1)(3x-2)

C= 4x^2 - 9
C= (2x)^2 - 3^2
C= (2x-3)(2x+3)

D= (2x+3)^2 - 2x (2x+3)
D= (2x+3)(2x+3-2x)
D= (2x+3)(3)
D= 3(2x+3)

E= (5x-3)^2 - 36
E= (5x-3)^2 - (6)^2
E= (5x-3-6)(5x-3+6)
E= (5x-9)(5x+3)

F= (1-x) - (3x-11)(1-x)
F= (1-x)(1-3x+11)
F= (1-x)(12-3x)
F= (1-x)*3(4-x)
F= 3(1-x)(4-x)

G= x^2 + 10x + 25
G= (x)^2 + 2*5*x + (5)^2
G= (x+5)^2

H= (7x+1)^2 - (2x-3)^2
H= (7x+1-2x+3)(7x+1+2x-3)
H= (5x+4)(9x-2)
