Politesse !

Développer :

A = 5(2x-7)

A = 5×2x+5×(-7)

A = 10x-35

B = -4(-3x+1)

B = -4×(-3x)+(-4)×1

B = 12x-4

C = 4-31(x-5)

C = 4-[3×x+3×(-5)]

C = 4-(3x-15)

C = 4-3x+15

C = -3x+19

D = 5x-5(-2x+1)

D = 5x-[5×(-2x)+5×1]

D = 5x-(-10x+5)

D = 5x+10x-5

D = 15x-5

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

E = 2×3x+2×5-(4×x+4×2)

E = 6x+10-(4x+8)

E = 6x+10-4x-8

E = 2x+2

F = 3-(x+2)

F = 3-x-2

F = -x+1

G = (x+2)-(4-x)

G = x+2-4+x

G = 2x-2

H = 7+(-2-x)

H = 7-2-x

H = 7-2-x

| = (4x-5)+(-x+2)

I = 4x-5-x+2

I = 3x-3

J = -(-x+3)+(-2x-7)

J= x-3-2x-7

J = -x-10

Factoriser :

Pour 15 :

A = 15x + 45

A = 15×x+15×3

A = 15(x+3)

Pour 6 :

B = 6x+24

B = 6×x+6×4

B = 6(x+4)

Pour 4 :

C= 4x-8

C = 4×x-4×2

C = 4(x-2)

Pour 9 :

D = 27x-9

D = 9×3x-9×1

D = 9(3x-1)

Pour 11 :

E = 11x-33

E = 11×x-11×3

E = 11(x-3)

Pour 9 :

F = 9x+9

F = 9×x+9×1

F = 9(x+1)

Factoriser :

A = 4x²+3x

A = x×4x+x×3

A = x(4x+3)

B = 7x²-x

B = x×7x-x×1

B = x(7x-1)

C = 2x+5x³

C = x×2+x×5x²

C = x(5x+2)

D = 4x²+8x

D = 4x×x+4x×2

D = 4x(x+2)

E = 5x²-15

E = 5×x²-5×3

E = 5(x²-3)

F = 2x²+8x⁴

F = 2x²×1+2x²×4x²

F = 2x²(4x²+1)

G = 5x³-x²+2x

G = x×5x²-x×x+x×2

G = x(5x²-x+2)

H = 4x³-4x²+8x

H = 4x×x²-4x×x+4x×2

H = 4x(x²-x+2)

Bonne soirée.
