300

Write the following in standard form:

12x - 18 - 5x² + 17x⁴

What is the leading degree and the leading coefficient?

Standard form: 17x⁴ - 5x² + 12x - 18 

Leading degree: 4 (Quartic)

Leading coefficient: 17

400

What is the degree of the following term?

-2x

500

Put the polynomial in standard form. Classify the polynomial by degree & number of terms:

 - 3x - 4x² - 7

Standard form:  - 4x² - 3x - 7

Leading degree: 2 (quadratic polynomial) 

3 terms so it is a trinomial
