If x+1/x=1,then find x^2+x+2/x^2(1-x)
​

if x+1/x=1 then x^2+x+2/x^2(1-x)=x+2×1-x=2x

(a)1

Step-by-step explanation:

x^2-x+1=0

root are -omega,-omega square

put -omega,-omega square in equation,

you get,(-omega square)+(omega square)+(omega)+(-omega)+1=1

answer:

4

Step-by-step explanation:

1+1+1+1=4

this is the required answer

don't know the answer , sorry

I can't understand the question

I dont know this answer

if, x+1

=> x= -1

p(-1)= (-1)^21+(-1)^18+(-1)^12+(-1)^9+(-1)^3+1

=(-1)+(1)+(1)+(-1)+(-1)+1

=0

if, x=1

p(1)=(1)^21+(1)^18+(1)^12+(1)^9+(1)^3+1

=  1+1+1+1+1+1

=  6
