Question

if x+1/x=5 then find the value of x²+1/x²?​

Answer 1

Answer:

Step-by-step explanation:

We have ,x- 1/x=5

Then x-1=5x

5x-x=-1

4x=-1

X=-1/4

Now we have the value of x

X^2-1/x^2=(-1/4)^2-1/(-1/4)^2=(1/16)-1/( 1/16)

(-15/16) × 16/1= -15

x+1/x =5

(x+ 1/x )² = 5²

5² = x² + (1/x)² + 2 × x × 1/x

25 = x² + 1/x² + 2

25 -2 = x² + 1/x²

Thus value of x² + 1/x² =23.
