Question

If (x+1/x)=6.Find the value of x^2 + 1/x^2

Answer 1

Answer:

x+1/x=6

squaring both sides we get:

x^2 +1/x^2 +2×x×1/x =36

x^2 +1/x^2 +2 =36

x^2+1/x^2=36-2

x^2+1/x^2=34

Answer 2

Answer:

Step-by-step explanation:

x+1/x=6

x+1=6*x

x+1=6x

6x-x=1

5x=1

x=1/5

x²+1/x²=(1/5)²+1/(1/5)²

(1/25)+1/(1/25)

(1+25/25)/1/25

(26/25)/(1/25)

26/25*25/1

26/1

26
