To write as a polynomial, just multiply every term int he first parenth by every term in the second parentheses.
It is like distributing:
For Example
a2(a-4) - 2a(a-4) + 3(a-4)
a3 - 4a2 - 2a2 + 8a + 3a - 12
Now combine like terms:
a3 - 6a2 + 11a -12 <---- that is your polynomial
now use the above examples and calculate ur question
