Bonjour jaurais besoin d'aide pour ces calculs:
o= 2xau carre+3x
P=4xau carré+8x
q=5n-5p
r=49-63a
s=ab-bc
63-7x= (9- )
15x-20= (3- )
6au carré-x= ×x- ×x=( - ) x
o= 2xau carre+3x
P=4xau carré+8x
q=5n-5p
r=49-63a
s=ab-bc
63-7x= (9- )
15x-20= (3- )
6au carré-x= ×x- ×x=( - ) x

Bonjour,Factoriser :
o= 2x²+3x
o = x (2x + 3)
P=4x²+8x
P = 4x (x + 2)
q=5n-5p
q = 5 (n - p)
r=49-63a
r = 7 (7 - 9a)
s=ab-bc
s = b (a - bc)
