For the expression y + 6 - 3, determine the coefficient for the variable term.

3

Step-by-step explanation:

Determine the coefficient of y+ 6 - 3 in the binomial expansion y+ 3(2-1)  

3(2+-1) + y = + 3(2) - (3)^-1   = 3

= y + 6 - 3   = y+3

remember to add a minus sign before every second term then a plus.

Now we see that in the term where y is in factor 3 as asked in the question (this is the term  2(3), the coefficient is therefore 3.

the answer is b.)
