aider moi c'est pour dm1 = 32 + 4 + 5 + 2( − 1) = 4(2 − 5) + 3( − 1) = (2 − 3) − 2(32 − 5) = (3 + 1)(2 + 3) = (2 − 1)( − 3) = (3 − 1)(2 − 3) + ( + 2)(3 − 5) = (

Bonjour

= 32 + 4 + 5 + 2( − 1)

= 41 - 2

= 39

= 4(2 − 5) + 3( − 1)

= 4 x (-3) - 3

= (-12) - 3

= (-15)

= (2 − 3) − 2(32 − 5)

= (-1) - 2 x 27

= - 1 - 54

= (-55)

= (3 + 1)(2 + 3)

= 4 x 5

= 20

= (2 − 1)( − 3)

= 1 x (-3)

= (-3)

= (3 − 1)(2 − 3) + ( + 2)(3 − 5)

= 2 x (-1) + 2 x (-2)

= (-2) + (-4)

= (-6)

= (2 − 1)(2 + 3) − (3 − 4)( − 5)

= 1 x 5 - (-1) x (-5)

= 5 - 5

= 0
