Question

Développer et simplifier au maximum :

A = 4(2x-6)
B= 7(8x+1)
C= 2(x+3) +6 (4x-2)
D= 2x(6x²+3x-1)
E= 3x(y-4xy)

2 Réponse

  • A = 4(2x-6) = 8x-24

    B= 7(8x+1) = 56x+7

    C= 2(x+3) +6 (4x-2) = 2x+6+24x-12 =26x -6

    D= 2x(6x²+3x-1) = 12xau cube +6x² -2x

    E= 3x(y-4xy)
      = 3xy -12x²y
  • bonsoir

    a = 8 x - 24

    b = 56 x + 7

    c = 2 x +6 + 24 x - 12 = 26 x - 6

    d = 12 x² + 6 x² -2 x = 18 x² - 2 x
    e = 3 xy - 12 xy = - 9 xy
