Question

if x=x+1/2=5 find x^2+1/2^2​

Answer 1

Step-by-step explanation:

x+1/2=5

Squaring both sides,

x^2+1/2^2=5^2

x^2+1/2^2=25

Answer 2

Correct question should be

x + (1/x) = 5

To find x^2 + (1/x)^2 = ?

Given:

x + (1/x) = 5 ——> 1

Squaring on both sides,

(x + (1/x))^2 = 5^2

x^2 + (1/x)^2 + 2*x*(1/x) = 25

x^2 + (1/x)^2 + 2 = 25

x^2 + (1/x)^2 = 25 - 2

x^2 + (1/x)^2 = 23 ——> Answer
