Question

if x2+1/x2=51,then find the value of x+1/x​

Answer 1

Answer:

x2 + 1/x2 = 51

x +1/x =?

Using the identity ((x +y)2= x2 +y2 + 2xy) we get,

(x +1/x)2 = x2 + 1/ x2 +2x(1/x)

Lets substitute the known value here!

(x +1/x)2 = 51+2

(x + 1/x)2 = 53

(x + 1/x) = √53

Therefore the value of (x+1/x) is √53! Hope this helps!!!!!!

Answer 2

Step-by-step explanation:

isme x+1/x ka square karo phir identity ka use karke solve karo phir

jo given de rakha h uska use kar ke ho jayega
