[2 MARKS]

Answer:
:
Steps: 1 Mark
Answer: 1 Mark
As per the question:
We have to find out the sum of the numerical coefficients of the expression

2 x^{2} + 31 y - 5 x y

The numerical coefficient of

2 x^{2}

2

The numerical coefficient of

31 y

31

The numerical coefficient of

- 5 x y

- 5

Sum of the coefficients = 2 + 31 - 5 = 28
Hence, the sum of the numerical coefficients of the expression

2 x^{2} + 31 y - 5 x y

28
