(a+ 1/a +2)^2 = 4

square roting both sides

(a +1/a +2) = +/- 2

case 1

a + 1/a + 2 = 2

a + 1/a = 0

squaring both sides

a^2 + 1/a^2 + 2 = 0

a^2 + 1/a^2 = -2

not possible as per question

case2

a + 1/a + 2 = -2

a + 1/a = -4

squaring both sides

a^2 + 1/a^2 + 2 = 16

a^2 + 1/a^2 = 14

hence answer = 14

amitnrw: 14 is also one of the answer dear
