Bonjour
A = 3 x / x +2 - 3/2
tu mets sous dénominateur x + 2
A = 3 x / x +2 - 3 x / x + 2
a = 6 x sur x + 2
1/2 ( x - 2) - ( x -3) = 1/2 x + 2
x/2 - 2/2 - x + 3 = x /2 + 2
x/2 - 2 x/2 - x/2 = 4/2 - 6/2 + 2/2
- 2 x = 0
x = 0

3. 1/2(x-2)-(x-3)=-1/2x+2
1/2x-1-x+3=-1/2x+2
1/2x+1/2x-x=1-3+2
x-x=3-3
0=0
donc S = tous les nombres réels
