Question

(x+1/x) = 3 then (x²+1/x²) ??​

Answer 1

Answer:

7

Step-by-step explanation:

(x + 1/x)2 = x2 1/x2 +2

(3)2 = x2+1/x2 +2 9- 2 x2 +1/ x2 = x2+1/x2 =7

Answer 2

Answer:

7

Step-by-step explanation:

(x+1/x)=3

squaring both side

(x+1/x)^2=(3)^2

x^2+1/x^2+2×x×1/x=9

x^2+1/x^2+2=9

x^2+1/x^2=9-2

x^2+1/x^2=7

Hence, the required answer is 7
