Which example illustrates the commutative property of addition for polynomials?

(2x^2 + 5x) = –(–2x^2 – 5x)

(2x^2 + 5x) + 0 = (2x^2 + 5x)

(2x^2 + 5x) + (4x^2 – 4x) = 2x^2 + 5x + 4x^2 – 4x

(2x^2 + 5x) + (4x^2 – 4x) = (4x^2 – 4x) + (2x^2 + 5x)

If they are all in the same order, it;s not commutative.

When not 100% sure of what a term means, I look it up.  Why not look up "commutative?"
