i can put x^51 as t , then still t + 1/t cant be equal to 1
yeah thats the only trick here x=1 is the only sol so the ans will be 0

two kaha bhai one day hi bacha hai... wo bhi travel mein chala jaayega
4563
@sampras but x =1 doesnt satisfy x^51 + 1/x^51
4564

@watsnew24 Q. x+1/x = 1, find x^12+x^9+x^6+x^3+1 = ? kaise karna hai???
4567

@sampras minimum value possible of x +1/x function is 2 , it cant be 1 in any case

kaise karna hai??
bhai x+1/x =1... so x^2-x+1 = 0, so x^3-1 = 0 this gives x=1 now calculate

yaar itna socha nhi ki possible hoga ya nhi....

trick padi hai giving answer as 1.......


x^2-x+1 = 0

break up karne par x^3+1 ki value x+1 & x^2-x+1 ho jayegi

so poora 0 ho jayega shahyad
