x+1/x=5, (x+1/x)=?

Answer 1

since they are the same equations, unless you type wrongly or it's me who interpreted wrongly, the answer is the same...

Answer 2

5

Answer 3

x+1/x=5

Answer 4

x+1/x=5, (x+1/x)=5

Answer 5

Probably going out on a limb here, but my crystal ball
tells me you want to know the value of (x^2 + 1/ x^2).
Even if I'm not psychic, it is interesting, or maybe I'm psycho!

x + 1/x = 5
Squaring both sides:
x^2 + 2 + 1/x^2 = 25
So, x^2 + 1/x^2 = 23.

Let's do another one.

x + 1/x = 5
Cubing both sides:
x^3 + 3x + 3/x + 1/x^3 = 125
From the middle two terms, take out the factor 3:
x^3 + 3(x + 1/x) + 1/x^3 = 125
But x + 1/x = 5,
so, x^3 + 15 + 1/x^3 = 125
Therefore, x^3 + 1/x^3 = 110.

Isn't that wonderful.
I'm sure you could make a project out of this.
Now try the fourth power - getting more interesting?

Answer 6

I don't think they are the same.

My answer:

(x+1/x)= [1+(5-X)^2]/(5-X)

Is it right?

Answer 7

let us find the value of x
x+1/x=5
x+1=5x
x=5x-1
x-5x=-1
-4x=-1
4x=1
x=1/4
in the second equation,x=1/4
(x+1/x)=?
1/4+1/1/4
5/4/1/4
5/4*4
5
the answer is 5

Answer 8

It's 5. Brackets will not matter the answer

Answer 9

If you meant to say "x=?", then you need to multiply both sides of the equation by "x". Then you'll have a quadratic equation to solve. You could either complete the square, or use the quadratic formula to get a solution.

Answer 10

(x+1)/x=5
or,x+1=5x
or, 4x=1
or,x=1/4

x+1/x=1/4+1/1/4=1/4+4=4.25

Answer 11

Answer is
26 - 10X - X*X
