Bonjour

Développer et réduire les expressions obtenues lorsque cela est possible :

• 5 ( x + 2 ) = 5x + 10

• 7 ( 3 + 5x ) = 21 + 35x

• - 3 ( 4 – x ) = - 12 + 3x

• - 2 ( 2x – 9 ) = 4x + 18

• - 6 ( x + 3 ) = - 6x - 18

• 4 + ( x + 1 ) = 4 + x + 1 = x + 5

• 7x – ( 4 – 3x ) = 7x - 4 + 3x = 4x - 4

• - 2x + ( 8 – 3x ) = 2x + 8 - 3x = - x + 8

• 2 ( x² + 1 ) + ( - 3 x )² - ( x + 4 )

= 2x² + 2 - 3x² - x - 4

= - x² - x - 2.
