Explications étape par étape
Bonsoir
A = 6(x + 3)
A = 6 * x + 6 * 3
A = 6x + 18
B = -5(x - 2)
B = -5 * x - 5 * (-2)
B = -5x + 10
C = 3(-2x - 8)
C = 3 * (-2x) + 3 * (-8)
C = -6x - 24
D = -2(-3x + 2)
D = -2 * (-3x) - 2 * 2
D = 6x - 4
E = 5x(x + 2)
E = 5x * x + 5x * 2
E = 5x^2 + 10x
F = -5(4 - 2x)
F = -5 * 4 - 5 * (-2x)
F = -20 + 10x
G = 9x(x^2 - 2)
G = 9x * x^2 + 9x * (-2)
G = 9x^3 - 18x
H = (-5c - 5) - (-5c - 5)
H = -5c - 5 + 5c + 5
H = 0
I = -3(x - 7) - 3x
I = -3 * x - 3 * (-7) - 3x
I = -3x + 21 - 3x
I = -6x + 21
J = 6(x^2 + 7) + 6x(-x + 8)
J = 6x^2 + 42 - 6x^2 + 48x
J = 48x + 42
