Answer 1

How to find the sum of the coefficients for 5x^2 + 4xy – 3(x +2). Please explain.

Answer 2

so it can be zero

Answer 3

the coefficients in this expression are the numbers

Answer 4

Please can you explain

Answer 5

sorry not all the numbers - only those in front of variables
so they are 5, 4 and -3

Answer 6

sum of these = 6

Answer 7

so -6 is the constant number

Answer 8

yea

Answer 9

but the answer for this question is zero

Answer 10

oh ok - so they have included -6. You can regard a constant as the coefficient of x^0 that is 1. -6 = 6x^0.

Answer 11

-6 = -6x^0.

Answer 12

Thank you.I always learned that number without variable is constant.but it excludes for for only quadratic equations . Is it right

Answer 13

sorry but i'm not really sure - it appears that way.
