Hi;

For the first one you might try the substitution y = x^4.

That yields y^2 + y + 1

You can factor that maybe.

Okay but how. Please tell the formula or the general form being applied.

I do not know one, or if one exists. That is not even a cyclotomic polynomial.

That can be factored by using the quadratic formula.
