Bonjour,
Exercice 4 : Simplifier
A = 3 + 7 * x
A = 3 + 7x
A = 7x + 3
B = x * 5
B = 5x
C = 4 + 12 * x + 9
C = 4 + 12x + 9
C = 12x + 13
D = 3 * x * 5
D = 3x * 5
D = 15x
E = x * 3 * x
E = 3x * x
E = 3x²
F = 3 + 4 * x + 2 * 5 + x * 7 * x * x
F = 3 + 4x + 10 + 7x³
F = 7x³ + 4x + 13
G = 4x * 5x
G = 20x²
H = 2x * 3x²
H = 6x³
I = 4x * 5x + 4x * 3
I = 20x² + 12x
J = 3x * 4 + 3x * 10 + 3x * 4x² + 5 * 6
J = 12x + 30x + 12x³ + 30
J = 12x³ + 42x + 30
K = (2 - 7 * x) * (2 - 7 * x)
K = (2 - 7x) * (2 - 7x)
K = (2 - 7x)²
K = 2² - 2 * 2 * 7 + (7x)²
K = 4 - 28x + 49x²
K = 49x³ - 28x + 4
L = 5 * x * (21 - 7 * 3) + 3x * 2
L = 5x * (21 - 21) + 6x
L = 5x * 0 + 6x
L = 5x + 6x
L = 11x
M = (3 * x - 7) * 17 + (3 * 4 - 11) * x
M = (3x - 7) * 17 + (12 - 11) * x
M = 17(3x - 7) + x(12 - 11)
M = 17 * 3x + 17 *(- 7) + x * 12 + x * (- 11)
M = 51x - 119 + 12x - 11x
M = 52x - 119
En espérant t'avoir aidé(e).
Bonne journée.
