1, $$(13-4x)\sqrt{2x-3}+(4x-3)\sqrt{5-2x}=2+8\sqrt{16x-4x^2-15}$$
2, $$2\sqrt{2x+4}+4\sqrt{2-x}=\sqrt{9x^2+16}$$
3, $$\sqrt{x^2-x-6}+3\sqrt{x}=\sqrt{2(x^2+5x-3)}$$
1, $$(13-4x)\sqrt{2x-3}+(4x-3)\sqrt{5-2x}=2+8\sqrt{16x-4x^2-15}$$
2, $$2\sqrt{2x+4}+4\sqrt{2-x}=\sqrt{9x^2+16}$$
3, $$\sqrt{x^2-x-6}+3\sqrt{x}=\sqrt{2(x^2+5x-3)}$$
