Bonsoir,
Exercice 1 :
A = 5(2x-7)
A = 10x-35
B = -4(-3x+1)
B = 12x -4
D = 5x -5(-2x+1)
D = 5x +10x-5
D = 15x -5
E = 2(3x+5)-4(x+2)
E= 6x+10-4x-8
E = 2x+2
Exercice 2 :
A = (x+3)(x+4)
A = x²+4x+3x+12
A = x²+7x+12
B= (2x-3)(-x+2)
B= -2x²+4x+3x-6
B = 2x²+7x-6
C = (-4x+3)(2x+1)
C= -8x²-4x+6x+3
C = -8x²+2x+3
D = (7x-2)(5x-4)
D= 35x²-28x-10x+8
D = 35x²-38x+8
E = (-3x-4)(8x-7)
E = -24x²+21x-32x+28
E = -24x²-11x+28
Exo 3 :
A = 5+(2x-7)(4-3x)
A = 5+ (8x-6x²-28-21x)
A = 5 -6x²+29x-28
A = -6x²+29x-23
B = 3-(4x+1)(-x+2)
B= 3-(-4x²+8x-x+2)
B = 3- (-4x²+7x+2)
B = 3+4x²-7x-2
B= 4x²-7x+1
C= 5x-1 + (2x-3)(3x+1)
C = 5x-1 + (6x²+2x-9x-3)
C = 5x-1+6x²-7x-3
C = 6x²-2x-4
D = 4x²- (-5x+2)(x-3)
D = 4x²-(-5x²+15x+2x-6)
D = 4x²-(-5x²+17x-6)
D = 4x²+5x²-17x+6
D = 9x²-17x+6
E = (2x-3)(x+5)-4(2x-1)
E= 2x²+10x-3x-15-8x+4
E = 2x²-x-11
Bonne soirée
