$\LARGE{}2 \sqrt{32} + \sqrt{75} - \sqrt{48} - \sqrt{72} \\ \\ \LARGE{} {2}^{3} \sqrt{2} + 5 \sqrt{3} - 4 \sqrt{3} - 6 \sqrt{2} \\ \\\LARGE{} 8 \sqrt{2} + 5 \sqrt{3} - 4 \sqrt{3} - 6 \sqrt{2} \\ \\ \LARGE{}(8 - 6) \sqrt{2} \\ \LARGE{}2 \sqrt{2} + 5 \sqrt{3} - 4 \sqrt{3} \\ \LARGE{}(5 - 4) \sqrt{3} \\ \LARGE{}1 \sqrt{3} \\ \LARGE{} \sqrt{3} \\ \\ {\large\boxed{\boxed{  { \LARGE \tt 2 \sqrt{2} + \sqrt{ 3} }}}}$
