Question

If x-1/x =12 find the value of x^2+1/x^2​

Answer 1

If x-1/x =12 find the value of x^2+1/x^2

Answer 2

x-¹/x = 12

or, ( x-¹/x)² = 12²      (squaring both sides)

or,  x²+¹/x²-(2×x×1/x) = 144

or, x²+¹/x²-2 = 144

or, x²+¹/x² = 144+2

or, x²+¹/x² = 146

Hence, x²+¹/x² = 146

Hope this helps you to get to your answer.
