Bonjour qui peut m’aider pour mon travail de math ?

Réponse :

A = 6x + 2x

A = 8x

B =5x x 3x

B = 15x²

C = -3x + 8x

C = 5x

D = -2x x 4x

D = -8x²

E = 7 - 2x

E = impossible

K = 5x² - 9x²

K = -4x²

I = 3 + 2x²

I = impossible

H = -4x + 3x

H = -1x

O = 5(-4x) + 2(3x)

O = 5 x -4x + 2 x 3x

O = -20x + 6x

O = -14x

J = 4 x 2x²

J = 8x²

M = 2 x 3x - 5 x 2x

M = 6x - 10x

M = -4x

N = -3x x 2x + 4 x (-2x²)

N = -6x² + (-8x²)

N = -14x²
