Шаг 1: Раскроем скобки.
\[\sqrt{0.09} - (\sqrt{12} - \sqrt{2})(2\sqrt{3} + \sqrt{2}) = \sqrt{0.09} - (\sqrt{12}\cdot 2\sqrt{3} + \sqrt{12}\cdot \sqrt{2} - \sqrt{2}\cdot 2\sqrt{3} - \sqrt{2}\cdot \sqrt{2})\]
\[= \sqrt{0.09} - (2\sqrt{36} + \sqrt{24} - 2\sqrt{6} - 2) = \sqrt{0.09} - (2 \cdot 6 + 2\sqrt{6} - 2\sqrt{6} - 2) = \sqrt{0.09} - (12 - 2)\]
\[= 0.3 - 10 = -9.7\]
Ответ: -9.7
