Question

Numerical coefficient of '-pq' will be
A. 1
B. -1
C. -p
D. -pq

Answer 1

Option A is the correct one.

Reason:

Because 1 x (-pq) = -pq

[because (+) x (-) = (-) ]

Other options are wrong because:

B) -1 x (-pq) = pq [because (-) x (-) = (+) ]

C) -p x (-pq) = p²q [because (-) x (-) = (+) ]

D) -pq x (-pq) = pq [because (-) x (-) = (+) ]
