Question

if x + 1/x = 4 then find the value of x²+ 1/x²

Plz solve this...

Answer 1

Answer:

18 is the answer of this question

Answer 2

x + 1/x =4

squaring both sides

(x+1/x)²=(4)²

x²+1/x²-2*x*1/x =16

x and 1/x will be cancelled

so

x²+1/x²=16+2

x²+1/x²=18

I think so this is your answer
