Bonjour, c'est un dm urgent pour demain aidez moi svp : EXO - Factoriser les expressions :
A = (-7x - 6) (x + 5) + (8x - 9) (x + 5)
B = 5 (5 - 2x) (x+1) + 5 (8x - 5) (x+1)
C = 6 (x + 1) (3x - 2) - 2(2 - 5x) (x + 1)
D = 16(x - 1)² - 8(x-1) (x+5)
A = (-7x - 6) (x + 5) + (8x - 9) (x + 5)
B = 5 (5 - 2x) (x+1) + 5 (8x - 5) (x+1)
C = 6 (x + 1) (3x - 2) - 2(2 - 5x) (x + 1)
D = 16(x - 1)² - 8(x-1) (x+5)
