Question

if x-1/x =2, then show that x'2+1/x'2=x'4+1/x'4 ,.
please solve this​

Answer 1

Answer: Proved

Step-by-step explanation:

$\frac{x-1}{x}=2$

or, 2x=x-1

or, x=-1

$\frac{x^{2}+1}{x^{2} }$=$\frac{(-1)^{2}+1 }{(-1)^{2} }$=$\frac{1+1}{1}$=2

$\frac{x^{4}+1}{x^{4}}$=$\frac{(-1)^{4}+1 }{(-1)^{4} }$=$\frac{1+1}{1}$=2

or, $\frac{x^{2} +1}{x^{2} } =\frac{x^{4}+1 }{x^{4} }$
