Factoriser les expressions suivantes.
A = (-3x +3)2 - 1
A = (-3x + 3)^2 - 1^2
A = (-3x + 3 - 1)(-3x + 3 + 1)
A = (-3x + 2)(-3x + 4)
B = (9x-7)(-10x+1)+(-10x+10) (-10x+1)
B = (-10x + 1)(9x - 7 - 10x + 10)
B = (-10x + 1)(-x + 3)
C = 4x2 - 36 - (2x + 6) (-3x -9)
C = (2x)^2 - 6^2 - 2(x + 3) * (-3)(x + 3)
C = (2x - 6)(2x + 6) + 6(x + 3)^2
C = 2(x - 3) * 2(x + 3) + 6(x + 3)^2
C = (x + 3)[2(x - 3) + 6(x + 3)]
C = (x + 3)(2x - 6 + 6x + 18)
C = (x + 3)(8x + 12)
C = (x + 3) * 4(2x + 3)
C = 4(x + 3)(2x + 3)
D = 49x2 - 36
D = (7x)^2 - 6^2
D = (7x - 6)(7x + 6)
E = (10x- 7) - (10x-6) (10x - 7)
E = (10x - 7)(1 - 10x + 6)
E = (10x - 7)(-10x + 7)
F=(-2x - 10)2 + (-2x - 10) (9x - 4)
F = (-2x - 10)(-2x - 10 + 9x - 4)
F = -2(x + 5)(7x - 14)
F = -2(x + 5) * 7(x - 2)
F = -14(x + 5)(x - 2)
