C = x(x-5)+(-5+x)(7x-3)
D= (6-2)(az - 4) -(6-2)(3 + 5x)
aider moi svp?​

Sagot :

C=x^2 -5x -35x +15 +7x^2 -3x
=8x^2 -43x +15

D= 6az -24 -2az +8 - (18 + 30x -6 -10x)
= 6az -24 -2az +8 -18 -30x +6 +10x
= 4az -20x -28

Bonsoir,

C=xcarré-5x-35x+15+7xcarré-3x

=8xcarré-43x+15

D=6az-24-2az+8-18+30x-6-10x

=4az-40+20x

Je précise que le carré c’est le petit 2
