									Write each expression in standard form. Then identify each polynomial by its degree and number
of terms.
1.

           2x2 – 4 + 3x; quadratic trinomial
           2x2 + 3x – 4; quadratic binomial
           –2x2 + 3x – 4; quadratic trinomial
           –2x2 + 3x – 4; quadratic binomial

2.
2b2 – 4b3 + 6 (2 points)

           2b2 – 4b3 + 6; quadratic trinomial
           –4b3 + 2b2 + 6; cubic trinomial
           –4b3 + 2b2 + 6; quadratic trinomial
           2b2 – 4b3 + 6; cubic trinomial

3.
