Question

lf X + 1/x =5, then x2+ 1/x2=​

Answer 1

Step-by-step explanation:

❤ hellp good morning your answer mate ❤...

Given x + 1 /x ) = 5

Given x + 1 /x ) = 5We need to find X2+ 1 / x2

Given x + 1 /x ) = 5We need to find X2+ 1 / x2( x + 1 / x )2 = 25

Given x + 1 /x ) = 5We need to find X2+ 1 / x2( x + 1 / x )2 = 25= x2 + 1 / x2 + 2 (x)(1)(1/x) =25

Given x + 1 /x ) = 5We need to find X2+ 1 / x2( x + 1 / x )2 = 25= x2 + 1 / x2 + 2 (x)(1)(1/x) =25= x2 + 1/x2 + 2 = 25

Given x + 1 /x ) = 5We need to find X2+ 1 / x2( x + 1 / x )2 = 25= x2 + 1 / x2 + 2 (x)(1)(1/x) =25= x2 + 1/x2 + 2 = 25= X2 + 1 / x2 = 25 – 2

Given x + 1 /x ) = 5We need to find X2+ 1 / x2( x + 1 / x )2 = 25= x2 + 1 / x2 + 2 (x)(1)(1/x) =25= x2 + 1/x2 + 2 = 25= X2 + 1 / x2 = 25 – 2= X2+ 1 / x2=23

Given x + 1 /x ) = 5We need to find X2+ 1 / x2( x + 1 / x )2 = 25= x2 + 1 / x2 + 2 (x)(1)(1/x) =25= x2 + 1/x2 + 2 = 25= X2 + 1 / x2 = 25 – 2= X2+ 1 / x2=23Hence X2+ 1 / x2= 23
