If we have:
"P= (n^3) + (n^2)"
Namely:
"P=(n*n*n) + (n*n)"
And P is even,
then, what can we say about n?
Is it even or odd?

Hi Lady!
No! No!!
This isn't made by myself!
Believe me please!!
Even you can read its tag. I've written "Mathematical" there.

.
n^3=n*n*n
n^2=n*n
In fact "^" is the sign of power.
Also, I've added it in the question just now.
Thank you for your attention.
Both. n can be both even or odd;
P = n^2 *(n+1)
Either n+1 or n^2 must be even in order that P is even.So if n+1 is even, then n is odd.
And if n^2 is even, then n is even.
Thanks for the puzzle.

Well done, Zahra!
It is right exactly.
None of them!
20/15!!
