Bonsoir,

Réponse :

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

(x + 1)(x + 2) - 2 = 0

x(x + 2) + 1(x + 2) - 2 = 0

x² + 2x + x + 2 - 2 = 0

x² + 3x = 0

x(x + 3) = 0

x = 0          x + 3 = 0

x = 0          x = -3

(3x - 5)² = 0 ​

(3x - 5)(3x - 5) = 0

   3x - 5 = 0    

     3x = 5              

     x = 5/3          

    x = 5/3

The bagel data also reflect how much personal mood seems to affect honesty. Weather, for instance, is a major factor. Unseasonably pleasant weather inspires people to pay at a higher rate. Unseasonably cold weather, meanwhile, makes people cheat prolifically; so do heavy rain and wind. Worst are the holidays. The week of Christmas produces a 2 percent drop in payment rates—again, a 15 percent increase in theft, an effect on the same magnitude, in reverse, as that of 9/11. Thanksgiving is
