Distributive Property is used.

%28y%2B3v%2B7%29%285y-6v%29
%285y-6v%29%289y%2B3v%2B7%29
%285y-6v%29%289y%29%2B%285y-6v%29%283v%29%2B%285y-6v%29%2A7 -------distributive property
45y%5E2-54vy%2B15vy-18v%5E2%2B35y-42v --------distributive property again
45y%5E2-54vy%2B15vy%2B35y-42v-18v%5E2
highlight%2845y%5E2-39vy%2B35y-42v-18v%5E2%29, DONE.
