Bonjour,

distributivité:

Exemple :

3(4x+2= 3*4x  + 3*2 =  12x +6

3-6x

 2x+2 - 8x -12 = -6x -10

12x² -8x

4x³ -7x²

8-4x

6x +3 -2x -8

10x² -15x

5x³ -2x²

bonjour

3 ( 1 - 2 x ) = 3 - 6 x

2 ( x + 1 ) - 4 ( 2 x + 3 ) = 2 x + 2 - 8 x - 12 = - 6 x- 10

4 x ( 3 x - 2 ) = 12 x² - 8 x

x² ( 4 x - 7 ) = 4 x ³ - 7 x²
