Exercice 1
Factorise les expressions suivantes :
A = x2 - 64
B = (2x + 4) (3x +7) + (4x+ 2) (2x + 4)
C = 16x2 - 40x + 25
D = (x – 5) (x + 9) + (x + 9) (2x - 1)
+
E = x2 + 12 x + 36
F = (5x – 2) (7x – 5) - x (5x – 2)
G=-8 (5x – 7) + (5x - 7) (x + 2)
H = (x + 4) (x + 3) - 5 (x + 3)
I = 9x2 - 0,25
J = (x + 9) (x – 8) + (5x + 1) (x + 9)
Merci d’avance
