    Oh I though the two was just a number on the outside. That changes things drastically!

    @Study23 sometimes problems are posted incorrectly You are correct to assume that the 2 needed to be distributed. I had a feeling it was a power. No harm

    You need to factor it out. \(\ \huge (-3x-4y)^2 \). Thats the same as \(\ \huge (-3x-4y)(-3x-4y) \). Foiling, that leaves \(\ \huge 9x^2 + 24xy + 16 y^2 \).
