Bonsoir
factoriser les expressions suivantes:
= -5(2-4)+(2-4)(+3)
= (2 - 4)(-5 + 3)
= (-6)(-2)
= 12
= (-7)(3-5)-(3-5)(2-9)
= (3 - 5)(-7 - 2 + 9)
= (3 - 5)(-9 + 9)
= (-2) * 0
= 0
ℂ= (-4+1)(+2)-(-4+1)aux carre
= (-4 + 1)(2 + 4 - 1)
= (-3)(6 - 1)
= (-3) * 5
= (-15)
=(6-5)(-4)+(6-5)
= (6 - 5)(-4 + 1)
= 1 * (-3)
= (-3)
=(3-6)(+8)+(-2)(2-5)
= 2[4(3 - 6) - 2 + 5]
= 2(4 * (-3) + 3)
= 2(-12 + 3)
= 2 * (-9)
= (-18)
