Question

if x minus one upon x is equal to 5 find the value of x square + 1 upon x square​

Answer 1

Answer:

The correct answer is 27

Step-by-step explanation:

x-1/x=5

find x²+1/x²?

(x-1/x)²= x²- 2×1/x×x+1/x²

(5)²=x²+1/x²- 2

25+2=x²+1/x²

27=x²+1/x²

Answer 2

anwer is 27

Step-by-step explanation:

(x-1/x)=5

squaring both sides

(x-1/x)^2=(5)^2

x^2+1/x^2-2=25

x^2+1/x^2=25+2

x^2-1/x^2=27
