[tex]c = \sqrt{12} \times ( \sqrt{32} - 3 \sqrt{3}) - 4(7 + 2 \sqrt{6}) \\ \\ c = 2 \sqrt{3}(4 \sqrt{2} - 3 \sqrt{3}) - 4(7 + 2 \sqrt{6}) \\ \\ c = 8 \sqrt{6} - 18 - (28 + 8 \sqrt{6}) \\ \\ c = 8 \sqrt{6} - 18 - 28 - 8 \sqrt{6} \\ \\ c = (8 \sqrt{6} - 8 \sqrt{6}) + ( - 18 - 28) \\ \\ c = - 46 [/tex]
[tex]d = \sqrt{48} \times ( \sqrt{8} - \sqrt{3}) - 2 \sqrt{2} \times (4 \sqrt{3} - \sqrt{2}) \\ \\ d = 4 \sqrt{3}(2 \sqrt{2} - \sqrt{3}) - 2 \sqrt{2}(4 \sqrt{3} - \sqrt{2}) \\ \\ d = 8 \sqrt{6} - 12 - (8 \sqrt{6} - 4) \\ \\ d = 8 \sqrt{6} - 12 - 8 \sqrt{6} + 4 \\ \\ d = (8 \sqrt{6} - 8 \sqrt{6}) + ( - 12 + 4) \\ \\ d = - 8 [/tex]
