Coefficient of a when 9a^2 - 18a is divided by (a - 2)
To find the coefficient of a, we need to perform long division as shown below:
9a - 18
(a - 2) | 9a^2 + 0a - 18
9a^2 - 18a
------------
18a - 18
18a - 36
--------
18
Therefore, the remainder is 18 and the quotient is 9a + 18. The coefficient of a in the quotient is 9, so the answer is option B) 9.
