D.) 8x6 + 8x4y2 - 5x3y3 + x2y4 - 7xy5

Marcus states that the polynomial expression 3x3 - 4x2y + y3 + 2 is in standard form. Ariel states that it should be y3 - 4x2y + 3x3 +2. Explain which student is correct and why.

They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree. Ariel has the exponents on the y variable in descending order from the highest degree to the lowest degree.
