Answer:
-1
Step-by-step explanation:
(Note, your question is actually either incorrect, or you have missed a part after +1 at the end, we should fins the value of a^2 + 1/a^2)
(a+1/a)=1
Square on both sides, we get:
a^2 + 1/(a^2) + 2(a)(1/a) = 1^2 = 1
=> a^2 + 1/a^2 = 1 - 2 = -1
Therefore, value of a^2 + 1/a^2 = -1
