X²P+5⁵x

It seems that you have provided a polynomial expression: x²P + 5⁵x. However, there are a few issues with this expression that need to be addressed before proceeding.

1. The notation for "P" is unclear. Is "P" a separate variable or is it meant to be multiplied by the x² term? If it is a separate variable, please provide its value or further clarify its nature. If it is meant to be multiplied, it needs to be written as x² * P.

2. The exponent of 5⁵x is written with a superscript, which is not a standard notation. It should be written as 5^5x or 5^(5x).

Once these issues are clarified, I will be able to assist you further in preparing for your university exams.
