Explanation:
5a\(^{1}\)
In polynomial, the term with highest exponent is the first term
Write terms in decreasing order of their exponents. Second term in the order is the second term of the polynomial.
Given polynomial is 4a\(^{1}\) + 5a\(^{1}\) - a2 + 6 Highest exponent of a is 4, then 3,
then 2 and then 0 i.e. the term containing constant 5a\(^{1}\) is the second term in the list
