Please solve this thank you so much :)

Answer 1

Hello Mate! Here is your answer:

Given,

= x²-9x+1 = 0

= Dividing the whole term by x, we get,

= x²/x - 9x/x + 1/x = 0

= x-9+1/x = 0

= x+1/x = 9

Now, According to the question,

= (x+1/x)³ = x³+1/x³+3(x+1/x)

= (9)³ = x³+1/x³+3(9)

= 729 = x³+1/x³+27

= 702 = x³+1/x³

The Value comes out to be 702.

I hope this helps and Welcome.
