Which expression represents the polynomial - 2x3-4x2+2x4+3x+4 rewritten in standard form?

10 x^4 - 8x^5

Explanation:

To write a polynomial in standard form, simplify and then arrange the terms in descending order. Ex. ax^2+ax+c

Then you would simplify

-2 x-5 (x^2x^2) - 2x4 (x^2x^3)

Simplify each term

= 10 x^4 - 8x^5
