Mrs. Allard asked her students to identify which of the polynomials below are in standard form and explain why.

I. 15x⁴ - 6x + 3x² - 1

II. 12x³ + 8x + 4

III. 2x⁵ + 8x² + 10x

Which students response is correct?

• Tyler said I and II because the coefficients are decreasing.

• Susan said only II because all the numbers are decreasing.

• Fred said II and III because the exponents are decreasing.

• Alyssa said II and III because they each have three terms.
