Question

(x+1/x)=10/3,then (x-1/x)² = ?

Answer 1

Answer:

x+1/x=10/3

3(x+1)=10×x

3x+3=10x

3=10x-3x

3=7x

7x=3

x=3/7

Answer 2

Answer:

64/9

Step-by-step explanation:

x+1/X=10/3

squaring on both sides

after solving we get,

x^2+1/x^2=82/9-----(1)

now, coming to the question

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

=(82/9)-2

=64/9
