Answer:
(x² + 1/x²) =23
Step-by-step explanation:
(x+1/x)²= 25
step1
use the property (a+b)^2
(a+b)^2
=a^2+b^2+2ab
step2
apply the property on (x+1/x)²
(x+1/x)²= x^2+1/x^2 + 2x×1/x
=x^2+1/x^2 + 2
step 3
(x+1/x)²=25
=x^2+1/x^2 + 2=25
=x^2+1/x^2=25-2
=x^2+1/x^2=23
(x² + 1/x²) =23
- hope this helps you
