Answer:

-200

Explanation:

We are given that:

  • P= -5
  • Q= -15

Simply insert this values into their correspondents in the equation given.

(-5 + (-15)) * (-5 - (-15))

Subtracting two negatives is like adding a positive and a negative.

(-5 + (-15)) * (-5 + 15)

Solve inside the parenthesis.

(-20) * (10)

Multiply.

-200
