case 2) 3x 5 + 3x 4 + x 3--------> A. Quintic trinomial
The degree of the polynomial is 5----> the greater exponent is elevated to 5
the number of terms is 3

case 3) x 2 + 3----------> B. quadratic binomial
The degree of the polynomial is 2----> the greater exponent is elevated to 2
the number of terms is 2

case 4) 2x 2 + x − 5 A------------> D. quadratic trinomial
The degree of the polynomial is 2----> the greater exponent is elevated to 2
