Question

if x-1/x =3find x2+1/x2​

Answer 1

Answer:. 5/2

Step-by-step explanation:

x - 1 = 3x (by rearranging)

-1 = 2x

x = -1/2

Hence X2 + 1/X2 = 1/2 +1 / 1/2

= 5/2

Answer 2

Answer:

(x - 1/x ) = 3

Squaring both sides :-

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

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

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

x^2 + 1/x^2 = 11
