Answer 2

The expression you provided is a polynomial: $X^4 - 2X^2 - 5$.

If you have a specific question or task related to this expression, please let me know, and I'll be happy to help you further. Here are some common tasks that can be done with a polynomial:

1. Simplify: If you want to simplify the expression, you can try to factor it or simplify it in some other way.

2. Evaluate: If you have a specific value for $X$ (a number), you can evaluate the expression by substituting that value for $X$ and calculating the result.

3. Solve: If you want to solve for $X$ in an equation where this polynomial is set to zero, you can try to find the roots of the polynomial (the values of $X$ that make the expression equal to zero).

If you have a specific question or task in mind, please let me know, and I'll provide a more detailed answer.
