Question
What will be the sum of the numerical coefficients in the below expression: [2 MARKS]
4x2+12xy−5y2−11y
4x2+12xy−5y2−11y
Answer:
:
Numerical Coefficients: 1 Mark
Sum: 1 Mark
The numerical coefficient of 4x2 = 4
The numerical coefficient of 12xy = 12
The numerical coefficient of −5y2 = -5
The numerical coefficient of −11y = -11
Sum of the coefficients = 4 + 12 - 5 - 11 = 0
Hence, the sum of all the numerical coefficients in the above expression is zero.
