Factoriser les expressions suivantes.
A= (-10x + 6)2 + (-5x + 2)(-10x + 6)
B = 4 – (72 – 7)
C = (-8x - 1)(- 1)-(-82 - 1)
Factoriser les expressions suivantes.
A= (-10x + 6)2 + (-5x + 2)(-10x + 6)

Réponse :
On factorise les expressions suivantes.
A= (-10x + 6)² + (-5x + 2)(-10x + 6)
A = (-10x + 6)[(-10x +6) + (5x +2)]
A = (-10x +6)(-10x +6 + 5x + 2)
A = (-10x +6)(-5x + 8)
B = 4-(7x-7)²
B = 2² - (7x - 7)²
B = [2 -(7x-7)][2 + 7x -7]
B = (2 -7x +7)(7x -5)
B = (9 - 7x)(7x - 5)
C = (-8x - 1)(- 1)-(-8x - 1)
C = (-8x -1)[ (-1) - 1]
C = -2(-8x -1)
