+25 Multiple and simply if possible.
\((2 \sqrt{3x}-2)(3\sqrt{3x}+5)\)
+343 I will use distributive property:
\((2\sqrt{3x}-2)(3\sqrt{3x}+5)<=>2\times 3(\sqrt{3x})(\sqrt{3x})+5\times2(\sqrt{3x})-2\times3(\sqrt{3x})-2\times5<=>6\times3x+10(\sqrt{3x})-6(\sqrt{3x})-10<=>18x+4(\sqrt{3x})-10\)
Finally \(18x+4(\sqrt{3x})-10\)
