Question
a=4*(2+x) b=3*(2y-5) c=-3*(2x+6) d=-3a(2a-4)
a=6*b+6t b=5x-5y c=2a+2 d=9x²-6xy
a=3+(x+6) b=x-(x-9) c=z+(-3-z²) d=6-(-a+8)
a=6*b+6t b=5x-5y c=2a+2 d=9x²-6xy
a=3+(x+6) b=x-(x-9) c=z+(-3-z²) d=6-(-a+8)

1. Réponse Aftershock
a = 4*(2+x)
a = 4x+8
b = 3*(2y-5)
b = 6y-15
c = -3*(2x+6)
c = -6x-18
d = -3a(2a-4)
d = -6a²+12a
(J'imagine qu'ici il faut factoriser)
a = 6b+6t
a = 6(b+t)
b = 5x-5y
b = 5(x-y)
c = 2a+2
c = 2(a+1)
d = 9x²-6xy
d = 3x(3x-2y)
a = 3+(x+6)
a = x+9
b = x-(x-9)
b = 9
c = z+(-3-z²)
c = -z²+z-3
d = 6-(-a+8)
d = a-2
