salut ^^ j'ai besoin d'aide pour des maths :

Factoriser les expressions ci-dessous :
a) (5x - 2) * (4x - 6) + (5x - 2) * (5x - 3) = ( ............. ) * ( ........................................ )
= ( ............... ) * ( .................. )

b) (8x + 4)² + (8x + 4) * (3x - 1) = ( ............. ) * ( ........................................ )
= ( ............... ) * ( .................. )

c) (2x + 7) (3x - 4) - 5 (3x - 4) = ( ............. ) * ( ........................................ )
= ( ............... ) * ( .................. )

d) (6x + 9) * (7x - 1) - (6x + 9) * (2x - 11) = ( ............. ) * ( ........................................ )
= ( ............... ) * ( .................. )

e) (3x + 2) * (8x + 5) - (10x + 7) * (3x + 2) = ( ............. ) * ( ........................................ )
= ( ............... ) * ( .................. )

désolé c'est un peu long, mais je vous remercie d'avance !
