Question

if (x+1/x) =1 , x2+1/X =?​

Answer 1

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

Answer 2

Answer:

Explanation:x+1/x=2

As we know that

(a+b)²=a²+b²+2ab

(x+1/x)²=(2)²

x²+1/x²+2=4

x²+1/x²=4-2

x²+1x²=2
