Question

M = (7x+5)+(3x-2)+(7x+5)(2x-3)

2 Réponse

  • = 7x+5+3x-2+(14x²-21x+10x-15)
    = 7x+5+3x-2+14x²-21x+10x-15
    = 14x²-x-12

    J'esqpere que je t aider
  • M = (7x + 5) + (3x - 2) + (7x + 5) (2x - 3)
    M = 7x + 5 + 3x - 2 + 7x * 2x + 7x * (- 3) + 5 * 2x + 5 * (- 3)
    M = 7x + 5 + 3x - 2 + 14x² - 21x + 10x - 15
    M = 14x² - x - 12
