Pick the expression that matches this description:
A monomial of the 2nd degree with a leading coefficient of
Choose 1

(Choice A)
A
3n^2
B
3n-n^2
C
3n^2-1
D
2n^3

Step-by-step explanation:

Monomial is just a kind of polynomial with just one term.

A monomial of 1st  degree means the variable should have power of 1. For example : etc.

Similarly, A monomial of 2nd  degree means the variable should have power of 2. For example : etc.

So, from all the options , the correct option is , where the variable has power of 2, i.e. its a monomial of the 2nd degree with a leading coefficient of 3.
