Bonjour,
Factoriser les expressions suivantes :
A = 4x ² - 36
A= (2x)² - 6²
A= (2x + 6)(2x - 6)
B = x² - 14x + 49
B = (x - 7)²
C = (2x + 4)(3x - 5) - (3x - 5)²
C = (3x - 5)(2x + 4 - (3x - 5))
C = (3x - 5)(2x + 4 - 3x + 5)
C = (3x - 5)(-x + 9)
D = (5x - 3)² - (4x + 5)²
D = (5x - 3 + 4x + 5)(5x - 3 - 4x - 5)
D = (9x + 2)(x - 8)
