bonjour aider moi svp merciii​

Réponse :

Factoriser les expressions suivantes:

L = 3 x + 3 y = 3(x+y)

N = 4 x² +3 x = x(4 x +3)

R = (2 x - 1)(3 x + 4)+(5+x)(2 x-1) = (2 x - 1)(3 x + 4 + 5 + X) = (2 x-1)(4 x+9)

T = (2 x-5)(x+2)-(2 x-5)(3 x-7) = (2 x-5)(x+2-3 x +7) = (2 x-5)(9-2 x)

M = 8 x + 15 x = 23 x

P = 2 x(x+1)+5(x+1) = (x+1)(2 x+5)

S = (4 x -3)(2 x+1)+(3-5 x)(4 x-3) = (4 x-3)(2 x+1+3-5 x) = (4 x -3)(4-3 x)

D = (3 x+2)(x+5)+ 3 x + 2 = (3 x+2)(x+5 + 1) = (3 x+2)(x + 6)
