p(2+x)-p(3a-x)=

To simplify the expression \( p(2 + x) - p(3a - x) \), we first recognize that it involves a polynomial function \( p \). Without a specific polynomial given for \( p \), we cannot simplify it further explicitly.

However, if you know the form of the polynomial \( p(x) \) (e.g., linear, quadratic, cubic, etc.), you can substitute \( 2+x \) and \( 3a-x \) into that polynomial and then perform the subtraction.

For example, if \( p(x) = ax^2 + bx + c \) (a quadratic polynomial), you would calculate:

1. \( p(2+x) = a(2+x)^2 + b(2+x) + c \)
2. \( p(3a-x) = a(3a-x)^2 + b(3a-x) + c \)

Then, substitute and perform the subtraction to find \( p(2+x) - p(3a-x) \).

If you provide more specific information about the polynomial \( p \), I could assist you further in simplifying the expression.
