Classify - 6x^5 + 4x^3 + 3x^2 + 11 by degree.

The degree of a polynomial can be obtained by looking at the highest exponent value among the terms in the polynomial. In this case, the term with the highest exponent value would be - 6x^5. Therefore, the degree of the polynomial is 5. Given this, the polynomial is considered to be a quintic polynomial.
