Question

if x-½ = ½ then find the value of 4x² + 4/x²​

Answer 1

Step-by-step explanation:

Given (x – 1/x) = 1/2 Squaring on both the sides, we get (x – 1/x)2 = (1/2)2 x2 – 2 + (1/x2) = 1/4 x2 + (1/x2) = (1/4) + 2 = (9/4) ∴ 4x2 + (4/x2) = 9

Answer 2

Answer:

Given That

x - 1/2 = 1/2

Step-by-step explanation:

x = 1/2 + 1/2

x = (1+1)/2

x = 2/2

x = 1

4x^2 + 4/x^2 = 4(1)^2 + 4/(1)^2 = 4 +4

4x^2 + 4/x^2 = 8
