$$\mathrm{16}{y}^{\mathrm{2}} +{xy}−\mathrm{15}{x}^{\mathrm{2}} \\ $$$$=\mathrm{16}{y}^{\mathrm{2}} +\mathrm{16}{xy}−\mathrm{15}{xy}−\mathrm{15}{x}^{\mathrm{2}} \\ $$$$=\mathrm{16}{y}\left({y}+{x}\right)−\mathrm{15}{x}\left({y}+{x}\right) \\ $$$$=\left(\mathrm{16}{y}−\mathrm{15}{x}\right)\left({x}+{y}\right) \\ $$
