Question

rezolvati in R ecuatia 1/x²-x+1/x=1

Answer 1

1/x la patrat-x+1/x=1
1/x la patrat-x+1/x=1 ,x diferit de0
1/x la patrat-x+1/x-1=0
1-x la puterea 3+x-xla puterea2totul pe x la patrat=0
1-x la puterea3+x-x la puterea2=0
-x la puterea3 -x la puterea2 +x+1=0
-x la puterea2*(x+1)=0        *semnul inmultirii
-(x la a2-1)*(x+1)=0
-(x-1)*(x+1)*(x+1)=0
-(x+1)*(x+1) la patrat=0
-(x-1)=0
 (x+1) la patrat=0

x=1
x=-1  xdiferit de 0
