Rezolvati ecuatia:
X + 1 supra X +2 + x + 2 supra x + 3 = 7 supra 6
Dau multe puncte si funda!!!!

Răspuns :

x+1/x+2+x+2/x+3=7/6
2x+1/x+5+2/x=7/6
2x+1/x+5+2/x-7/6=0
2x+1/x+23/6+2/x=0
12x²+6+23x+12/6x=0
12x²+18+23x/6x=0
12x²+18+23x=0
12x²+23x+18=0
x=-23±√23²-4•12•18/2•13
x=-23±√529-864/24
x=-23±√-335/24
