 = \sqrt{63} + \sqrt{28} - \sqrt{175} - \sqrt{50} \\ \\ = \sqrt{7 \times 9} + \sqrt{7 \times 4} - \sqrt{7 \times 25} - \sqrt{2\times 25} \\ \\ = (\sqrt{7} \times \sqrt{9} ) + ( \sqrt{7} \times \sqrt{4} ) - ( \sqrt{7} \times \sqrt{25}) - ( \sqrt{2} \times \sqrt{25} ) \\ \\ = 3 \sqrt{7} + 2 \sqrt{7} - 5 \sqrt{7} - 5 \sqrt{2} \\ \\ = 5 \sqrt{7} - 5 \sqrt{7} - 5 \sqrt{2} \\ \\ = - 5 \sqrt{2}
