52pq (-4)pq

To simplify the expression \(52pq (-4)pq\), you can follow these steps:

1. Multiply the coefficients:

   • \(52 \times -4 = -208\)

2. Multiply the variables:

   • Since you have \(pq\) and \(pq\), you combine them:
   • \(pq \cdot pq = p^2q^2\)

3. Combine everything:

   • The simplified expression is \(-208p^2q^2\).

Therefore, the final result is:

\[ -208p^2q^2 \]
