Final answer:
To write the polynomial in standard form, rearrange the terms by degree to get 2x^2 + 3x - 6. It is named a second-degree trinomial because the highest degree is 2 and it has three terms.
Step-by-step explanation:
To write the given polynomial 3x + 2x2 – 6 in standard form, we reorder the terms by degree from highest to lowest. So, the standard form is 2x2 + 3x – 6.
Next, we name the polynomial based on its degree and the number of terms. Since the highest power of the variable x is 2, this is a second-degree polynomial. Additionally, there are three terms, so it is called a trinomial. Therefore, the polynomial 2x2 + 3x – 6 is a second-degree trinomial.
