Stuck in it 3 days ago, please some help. It's a literal equation question.

Let's assume y₂ ≥ y₁.   This is wrong; we shouldn't assume that; the question writers did this problem incorrectly.  But we'll continue to get the answer they want you to choose.

A

The real answer is none-of-the-above.  It's bad when the teachers who write these questions don't really know what they're doing.

The correct answer is y₂ is ambiguous:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
