How can I complete the square for this problem..
\[x ^{10} - \frac{ 1 }{ 2 } + \frac{ 1 }{ 16x ^{10} }\]
is there a certain method to use to make it easier?
just for convenience, firstly, you can take \(x^{10} = y\)
\(y - \dfrac{1}{2} +\dfrac{1}{16y}\) does this atleast make it "look" easier to solve? :)
Hint: multiply every term in hartnn's last result by (y/y) (yes, that's y over y).
thank you! i will try the problem now
let us know if you get stuck :) if not, let us know your final answer so that we can verify :)
i will, thank you!
So far I have \[y+\frac{ 1 }{ 16y } + \frac{ 1 }{ 1024 }=\frac{ 1 }{ 2 }+ \frac{ 1 }{ 1024 }\] am i on the right track?

This is for making a common denominator! better if you try to make each of the denominator as `16y` |dw:1457759890787:dw|
