Bonjour,

E=

6+7 -x+3x²

= 3x²  -x +13

F=

4x-2x +9+9x²

= 9x² +2x +9

G=

13x² -5x -2 +11x² -4

= 24x² -5x -6

H=

-x-x²+2 -x² +10x

= -2x² +9x +2

bonjour

E = 6 + 7 - x + 3 x²

= 3 x² - x + 13

F = 4 x - 2 x + 9 + 9 x²

= 9 x² + 2 x + 9

G = 13 x² - 5 x - 2 + 11 x² - 4

= 24 x² - 5 x - 6

H = - x - x² + 2 - x² + 10 x

= - 2 x² + 9 x + 2
