For this case we have the following polynomials:
 3x2
 x2y + 3xy2 + 1
 We have then:

 For 3x2:
 Classification: polynomial of one variable:
 Degree: 2

 For x2y + 3xy2 + 1:
 Classification: polynomial of two variables
 Degree: 2 + 1 = 3
 Answer:
 The polynomial 3x2 is of one variable with a degree of 2.
 The polynomial x2y + 3xy2 + 1 is of two variables a with a degree of 3.
