Bonjour je dois développer et réduire les expressions suivantes
A=(x+3) (x-2)
B=(7-x) (5+x)
C=(x-5) (2x-7)
D=(3x-2) (5x+1)
E=(4-2x) (-1-3x)
F=(x+3) (x-3)
G=(2-x) (2+x)
H= (6x+7) (6x-7)
I=(x+6)2
J=(x-1)2
K=(3x-5)2
L=(2x+1)2
M=(2x+3)2
N=(4x-1)2
O=(5x+1) (5x-1)
svp c est pour demain

Je te laisse faire la suite :)
A = (x + 3) (x - 2)
A = x² - 2x + 3x - 6
A = x² + x - 6
B = (7 - x) (5 + x)
B = 35 + 7x - 5x - x²
B = - x² + 2x + 35
C = (x - 5) (2x - 7)
C =2x² - 7x - 10x + 35
C = 2x² - 17x + 35
D = (3x - 2) (5x + 1)
D = 15x² + 3x - 10x - 2
D = 15x² - 7x - 2
E = (4 - 2x) (-1 - 3x)
E = - 4 - 12x + 2x + 6x²
E = 6x² - 10x - 4
F = (x + 3) (x - 3)
F = x² - 3x + 3x - 9
F = x² - 9
G = (2 - x) (2 + x)
G = 4 + 2x - 2x - x²
G = x² + 4
H = (6x + 7) (6x - 7)
H = 36x² - 42x + 42x - 49
H = 36x² - 49
I = (x + 6) 2
I = 2x + 12
J = (x - 1) 2
J = 2x - 2
K = (3x - 5) 2
K = 6x - 10
L = (2x + 1) 2
L = 4x + 2
M = (2x + 3) 2
M = 4x + 6
N = (4x - 1) 2
N = 8x - 2
O = (5x + 1) (5x - 1)
O = 25x² - 5x + 5x - 1
O = 25x² - 1
J'espère t'avoir aidé.
