Bonjour pouvais-vous m'aider avec les calculs suivant: A=-2(3x+1)-3(x+3) B=5(6x-1)-(3-8x) C=2x(x+4)+x(1-x) D=-x(2-x)+(x▪-2x)-(3x▪-4) E=3x▪-(x▪-4x+5)-4x(x-3) F=(

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

A = -2*3x -2*1  -3*x -3*3

A = - 6x - 2 - 3x - 9

A = - 9x - 11

B = 5( 6x - 1) - ( 3 - 8x)

B = 5*6x + 5*-1 - 3 + 8x

B = 30x - 5 - 3 + 8x

B = 38x - 8

C = 2x (x + 4) + x (1 - x )

C = 2x*x + 2x*4 + x*1 + x*-x

C = 2x² + 8x + x - x²

C = x² + 9x

D= -x(2-x)+(x²-2x)-(3x²- 4)

D = -x*2 -x*-x + x² - 2x - 3x² + 4

D = - 2x + x² + x² - 2x - 3x² + 4

D = - 4x + 2x² - 3x² + 4

D = - x² - 4x + 4

E= 3x²- (x²- 4x + 5) - 4x(x-3)

E = 3x² - x² + 4x - 5 - 4x*x - 4x*-3

E =  2x² + 4x - 5 - 4x² + 12x

E = - 2x² + 16x - 5

F = (2x²-7x + 4) - 4x(-3 + 2x)

F = 2x² - 7x + 4  - 4x*-3 - 4x*2x

F= 2x² - 7x + 4 + 12x - 8x²

F = - 6x² + 5x + 4

G = 5x(-3x-6) - (15x² + 18x - 6)

G = 5x*-3x + 5x*-6 - 15x² - 18x + 6

G = - 15x² - 30x - 15x² - 18x + 6

G = - 30x² - 48x + 6
