Svp aider moi Exercice 2
Factoriser les expressions suivantes.
A = -(3x + 5) + (3x – 8) (3 x + 5)
B = 100.x2 – 81 – (10x + 9) (2 x – 10)
C = 100 x2 – 36
D=81 – (5 x – 1)2
E = (8x – 3)(-73 – 7) +(-73 – 7)?
F=-(6 x – 10) (-6x +10)+(-6x + 10) (2 – 10)
Exercice 3
Factoriser les expressions suivantes.
A= (-3x + 3)2 – 1
B = (9x— 7)(-10x+1)+(-10x+10)(-10x+1)
C = 4x2 – 36 – (2x+6)(-3x – 9)
D = 49x2 – 36
E = (10x – 7) – (10 - 6) (10 3 – 7)
F=(-2x – 10)2 + (-2x – 10) (9.2 – 4)
Merci d'avance
