Question

-5x^2-2x^3-4x write the polynomial in standard form then identify the polynomial by the number of terms

Answer 1

Answer: - 2x³ - 5x² - 4x, trinomial

Explanation:

When writing a polynomial, the standard form is to have the terms ordered from highest power to lowest power. 3 > 2, so we will reorder them as so;

- 5x² - 2x³ - 4x ➜ - 2x³ - 5x² - 4x

To identify the polynomial, we will look at the number of terms. This polynomial has three terms, so it is a trinomial.

- 2x³ - 5x² - 4x

[1] - 2x³

[2] - 5x²

[3] - 4x
