Final answer:
The question pertains to the factoring of a polynomial expression in mathematics, suited for the high school level. However, due to typographical errors, a complete factorization is not possible without the correct expression.
Step-by-step explanation:
The student's question asks about factoring an expression completely. The subject is clearly mathematics, and based on the content, it's appropriate for a high school level. To tackle this question, we would need to apply the rules of factoring, looking for common factors, patterns such as the difference of squares dx²-y², and possibly grouping terms to factor by grouping. This involves breaking down each term to its prime factors and then grouping together similar terms. Complex numbers and higher degree polynomials, such as terms with p and q raised to different powers or multiplied together, may require special attention. However, the expression provided contains typos or irrelevant parts, and thus it is not possible to factor it without the correct version of the expression.
