Best answer as selected by question asker.
`(n-5)^2 = 32`
`(n-5) = +-sqrt32`
`n = 5+-sqrt32`
`n = 5+-sqrt(16xx2)`
`n = 5+-4sqrt2`
So the answers are;
`n = 5+4sqrt2`
`n = 5-4sqrt2`

To solve, expand left side.
Then, set one side equal to zero.
And, use the quadratic formula to solve for n.
Hence, `n=5+4sqrt2` and `n=5-4sqrt2` .
