bonjour

(6x−6)(−6x+5)+(6x−6)(−4x−4)

=  ( 6 x - 6 ) ( - 6 x + 5 - 4 x - 4 )

= ( 6 x - 6 ) ( - 10 x + 1 )

= 6 ( x - 1 ) ( - 10 x + 1 )

Bonjour !

Je note A l'expression de ton énoncé.

[tex]A = (6x-6)(-6x+5)+(6x-6)(-4x-4)\\A = (6x-6)[-6x+5+(-4x-4)]\\A = (6x-6)(-6x+5-4x-4)\\A = (6x-6)(-6x-4x+5-4)\\A = (6x-6)(-10x+1)\\A = (x \times 6 - 1 \times 6)(-10x+1)\\A = 6(x-1)(-10x+1)[/tex]
