Answer: If the monomial has only one variable.
3x² is a monomial of the 2nd degree with a leading coefficient of 3.
Step-by-step explanation: Think of the your like terms such as the coefficents A polynomial which has only one term is called monomial.
The degree of a monomial is defined as the sum of all the exponents of the variables.
A leading coefficient is the number multiply to the variable.
