Answer 1

hlo mate ✌️

Given:

x - 1/x=2

To find :

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

---> ( x - 1/x)^2 = x^2 + 1/x^2 - 2

---> (2)^2 = {x^2 + 1/x^2} -2

---> x^2 + 1/x^2 = 4 + 2 = 6

Hope it helps ❣️

Answer 2

Answer:

6

Step-by-step explanation:

$x-\frac{1}{x}=2\\=>(x-\frac{1}{x})^2=2^2\\=>x^2+\frac{1}{x^2}-2x\frac{1}{x}=4\\=>x^2+\frac{1}{x^2}-2=4\\=>x^2+\frac{1}{x^2}=6$
