I have an image of the question :) please help.

Answer 1

Let's find the quotient of the first two terms:

$\begin{gathered} \frac{-8x^2y^3}{xy} \\ =-8xy^2 \end{gathered}$

The product of 4xy and WHAT should give us -8xy^2.

Let's call this WHAT as "A", so we can write:

$4xy(A)=-8xy^2$

To get this unknow, A, we can see that we have to divide -8xy^2 by 4xy, so

$\begin{gathered} 4xy(A)=-8xy^2 \\ A=\frac{-8xy^2}{4xy} \\ A=-2y \end{gathered}$

The unknown quantity is "-2y". From the drop-down, it's the
