1. Réponse MonsieurFirdown
Bonsoir
♧1. Developper et reduire :
A = -5(x+4)
A = -5×x -5×4
A = -5x - 20
B = -3(x-2)
B = -3x + 6
C = -4(5x-1)
C = -20x + 4
♧2. Factoriser chaque expresion :
A = 7x -14
A= 7×x + 7×(-2)
A = 7(x-2)
B = 12t + 6
B = 6(2t+1)
C = a² + 3a
C = a(a+3)
D = 4b² -12
D = 4 (b²- 3)
Voilà ^^ -

Bonsoir,
A = -5(x+4) B = -3(x-2)
A = -5 × x + (-5) × 4 B = -3 × x - (-3) ×2
A = -5x - 20 B = -3x + 6
C = -4(5x-1)
C = -4 × 5x - (-4) × 1
C = -20x + 4
A = 7x - 14 B = 12t + 6
A = 7 × x - 7 × 2 B = 6 × 2t + 6 × 1
A = 7(x-2) B = 6(2t+1)
C = a2 + 3a D = 4b2 - 12
C = a × 2 + a × 3 D = (2 × 2) × b × 2 - 2 × 6
C = a(2+3) D = 4 × 2(b-6)
