x+1/x = 12
do squaring on both sides
(x+1/x)^2 = (12)^2
x^2 + 1/x^2 + 2(x)(1/x) = 144
x^2 + 1/x^2 + 2 = 144
x^2 + 1/x^2 = 144-2
x^2 + 1/x^2 = 142
do squaring on both sides
(x+1/x)^2 = (12)^2
x^2 + 1/x^2 + 2(x)(1/x) = 144
x^2 + 1/x^2 + 2 = 144
x^2 + 1/x^2 = 144-2
x^2 + 1/x^2 = 142

(x+1/x) = 12
Squaring on both sides,
(x+1/x)² = 12²
x² + (1/x)² + 2(x)(1/x) = 144
x² + 1/x² = 144-2
x²+1/x² = 142
Hope it helps
