Question

x2 +1/x2=34 find x+1/x

Answer 1

x^2 + 1/x^2 =34....... find x+1/x

ANSWER:

firstly adding 2 on both sides of equation,

then we get,

x^2 + 1/x^2 + 2 = 34+2

(x+1/x)^2 = 36.........[(a+b)^2 = a^2 + 2ab + b^2]

now,

taking square root on both sides

x+1/x =6

so the final answer is

x+1/x = 6

Answer 2

Answer:

if it is given that x²+1/x² =34 then we can find value of x+1/x easily

let's start

on first step we will add 2 both side

so, it will be

x²+1/x²+2= 34+2

so, (x+1/x)²=36

to solve it we will remove square from the value of (x+1/x)² and put root on 36

then x+1/x = √36

x+1/x= 6
