X2*x-5

It looks like you might be looking to perform some mathematical operation or analysis involving the expression \( X^2 \cdot x - 5 \).

To clarify, this expression simplifies to:

\[ X^2 x - 5 \]

This can be interpreted as \( X^2 \) multiplied by \( x \) and then subtracting \( 5 \). If you need to solve for \( x \) or \( X \), or if you're looking for something specific (like finding its derivative, evaluating it at certain values, or factoring), please provide additional details!
