Question

How do you write the coefficient of the term -7pq?

Answer 1

It depends!

Explanation:

If both `p` and `q` are variables, then the coefficient is `-7`

If `p` is a constant and `q` a variable then the coefficient of `q` is `-7p`

If `q` is a constant and `p` a variable then the coefficient of `p` is `-7q`

If both `p` and `q` are constants then we could say that the coefficient of the `0`th power of some variable `x^0` (say) is `-7pq`, but we would usually simply describe `-7pq` as a constant term.
