Exercice 7:
Réduire les expressions littérales
au maximum.
A = 50 - X + 20
B = 10 -X + x + 5
C = x² - 4x - 5x² + 2x - 1
D = -3 + x - X² - 2x + 3x² - 8
E = X - 4 + 2 + x + x + 5
F = x² + 5x - 4 + 2x² - 9x + 7​

Sagot :

Réponse:

A=50+20-x

A=70-x

B=10+5-x+x

B=15

C=x²-5x²-4x+2x-1

C= -4x²-2x-1

D=x²+3x²-2x+x-3-8

D=4x²-1x-11

E=x+x+x-4+2+5

E=3x+3

F=x²+2x²+5x-9x-4+7

F=3x²-4x+3
