Bonsoir,
D=(12x+3)(2x-7)-(2x-7)²
D= 24x² - 84x + 6x - 21 - 4x² + 28x - 49
D= 20x² - 50x - 70

Bonsoir,
D = (12x + 3) (2x - 7) - (2x - 7)²
D = 24x² - 84x + 6x - 21 - (4x² - 28x + 49)
D = 24x² - 84x + 6x - 21 - 4x² + 28x - 49
D = 24x² - 4x² - 84x + 6x + 28x - 21 - 49
D = 20x² - 80x - 70

Bonsoir,D = (12x + 3) (2x - 7) - (2x - 7)²
D = 24x² - 84x + 6x - 21 - (4x² - 28x + 49)
D = 24x² - 84x + 6x - 21 - 4x² + 28x - 49
