Demonstrate that there are no perfect squares ending with $8$

It is impossible for $(x-1)^2+x^2+(x+1)^2$ to be a perfect square

If $u_1=1$ and $u_{n+1} = n+\sum_{k=1}^n u_k^2$, then $u_n$ is never a square.

Does digit $6$ always lead to $\ 25921=161^2\ $?

Find $n^2+58n$, such that it is a square number

If a prime $p$ divides $n^2$ then it also divides $n$ - Is this proof correct?
