Andru [333]

Answer:

$\sqrt{6} -3\sqrt{2}$

Step-by-step explanation:

$\sqrt{150} -\sqrt{96} -\sqrt{162} +\sqrt{72}$

$=\sqrt{25\cdot6} -\sqrt{16\cdot6} -\sqrt{81\cdot2} +\sqrt{36\cdot2}$

$=\sqrt{25}\sqrt{6} -\sqrt{16}\sqrt{6} -\sqrt{81}\sqrt{2} +\sqrt{36}\sqrt{2}$

$=5\sqrt{6} -4\sqrt{6} -9\sqrt{2} +6\sqrt{2}$

$=\sqrt{6} -3\sqrt{2}$
