Bonjour,

P=

-5x+7-8+3x +x

=-x -1

Q=

3x +5-x-3x+3

= -x+8

R=

-4x² -2x² +3x -1 -2x +3

= -6x² +x +2

A= 50x +40

B=54x -54x²

C = 12x +21 +8x -36

= 20x -15

D= 14x² -35x -2x² +5x

= 12x² -30x

E=  6x² +14x +15x +35

= 6x² +29x +35

F= 10x² -35x +16x - 56

= 10x² -19x -56

Bonjour

P = - 5x + 7 - 8 + 3x + x

P = - 5x + 3x + x + 7 - 8

P = - x - 1

Q = 3x + 5 - x - 3x + 3

Q = 3x - 3x - x + 5 + 3

Q = - x + 8

R = - 4x² - 2x² + 3x - 1 - 2x + 3

R = - 6x² + x + 2

A = 50x + 40

B = 56x - 54x²

C = 12x + 21 + 8x - 36

C = 20x - 15

D = 14x² - 35x - 2x² + 5x

D = 14x² - 2x² - 35x + 5x

D = 12x² - 30x

E = 6x² + 14x + 15x + 35

E = 6x² + 29x + 35

F = 10x² - 35x + 16x - 56

F = 10x² - 19x - 56.
