Explanation:
First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:
9a245a12a+6a23
Next, group like terms in descending order of the power of their exponents:
9a2+6a25a12a43
Now, combine like terms:
(9+6)a2+(512)a+(43)
15a2+(17)a+(7)
15a217a7
