Question

Mark the correct alternative in the following question:

The sum of the coefficients in the terms of 2x²y $-$ 3xy² + 4xy is

(a) $-$3 (b) 3 (c) 9 (d) 5

Answer 1

As, the coefficient in the term 2x²y = 2, the coefficient in the term $-$3xy² = $-$3 and the coefficient in the term 4xy = 4.

So, the sum of the coefficients in the terms of 2x²y $-$ 3xy² + 4xy = 2 + ($-$3) + 4 = $-$3 + 6 = 3

Hence, the correct alternative is option (b).
