M = 8x - 4
M = 4(2x - 1)
N = 2x² + 5x
N = x(2x + 5)
O = 24x + 12y
O = 12(2x + y)
P = (5x + 3)(-6x - 3) + 1(5x + 3)
P = (5x + 3)(-6x - 3 + 1)
P = (5x + 3)(-6x - 2)
Q = 5xy + 20xz
Q = 5x(y + 4z)
R = (3x + 5)(4x - 2) - (3x + 5)(5x - 4)
R = (3x + 5)(4x - 2 -(5x - 4))
R = (3x + 5)(4x - 2 - 5x + 4)
R = (3x + 5)(-x + 2)
J'espère t'avoir aidé.e :)
