Question

If x-1/x=1/3 , then write the value of 3x^2+3/x^2
pls gibe answer fast it is urgent

Answer 1

x-1/x = 1/3

or, x-1 = x/3

or, 3(x-1) = x

or, 3x - 3 = x

or, 3x - x = 3

or, 2x = 3

or, x = 3/2

Now ,

3x^2 + 3/x^2 = 3(3/2)^2 + 3/(3/2)^2

or, 3(9/4) + 3/9/4

or, 27/4 + 12/9

or, 27/4 + 4/3

or, 27(3) + 4(4) / 12

or, 81 + 16 /12

or,97/12 Answer.
