What is the degree of the polyomial 3x2 + 2x - 7?

  1. 1

  2. 2

  3. 3

  4. 4

The correct answer is: 3

The degree of a polynomial is the highest exponent of the variable present in the expression. In this question, the given polynomial has a term with x2, which has an exponent of 2. Therefore, the degree of the polynomial is 2. The other options, 1, 2, and 4, do not correspond to the highest exponent in the expression and are therefore incorrect. Option 3 (C) accurately represents the degree of the polynomial as 2.
