ANSWER
[tex]8v^2+16uv[/tex]
EXPLANATION
We want to find the product of the expression given.
To do this, use the term outside the bracket to multiply each of the terms in the bracket.
That is:
[tex]\begin{gathered} (-4v)(-4u)-(-4v)(2v) \\ 16uv-(-8v^2) \\ 16uv+8v^2 \\ \Rightarrow8v^2+16uv \end{gathered}[/tex]
That is the answer in standard form.
