Question

Find the second term of $4a^4+5a^3-a^2+6$.

• A. $4a^4$
• B. $5a^3$
• C. $-a^2$
• D. 6

Answer 1

The correct option is B $5a^3$

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 $4a^4+5a^3-a^2+6$

Highest exponent of $a$ is $4$, then $3$, then $2$ and then $0$ i.e. the term containing constant

$5a^3$ is the second term in the list

Hence, second term $=5a^3$
