Bonsoir,
a. (x + 1) (x - 8) = 0
x + 1 = 0 ou x - 8 = 0
x = - 1 x = 8
b. (5x - 3) (6 + x) = 0
5x - 3 = 0 ou 6 + x = 0
5x = 3 x = - 6
x = 3/5
c. (11 - 8x) (3x + 7) = 0
11 - 8x = 0 ou 3x + 7 = 0
- 8x = - 11 3x = - 7
x = 11/8 x = - 7/3
d. (7 - x) (x - 7) = 0
7 - x = 0 ou x - 7 = 0
- x = - 7 x = 7
x = 7
e. 2x (3x + 2) (3x - 1) = 0
2x = 0 ou 3x + 2 = 0 ou 3x - 1 = 0
x = 0 3x = - 2 3x = 1
x = - 2/3 x = 1/3
