Gpt: \(5x^2+3x+6=\left(7x+1\right)\sqrt{x^2+3}\)
giai pt sau
\(\sqrt{3x-1}-\sqrt{x+2}.\sqrt{3x^2+7x+2}+4=4x-2\)
\(x^2-5x+3.\sqrt{2x-1}=2.\sqrt{14-2x}+5\)
\(\left(x+1\right)\left(x+4\right)-3\sqrt{x^2+5x+2}=6\)
\(\sqrt{2X^2+3X-2}-3\sqrt{X+6}=4-\sqrt{2X^2+11X-6}+3\sqrt{X+2}\)
\(\sqrt{3X^2-7X+3}-\sqrt{X^2-2}=\sqrt{3X^2-5X-1}-\sqrt{X^2-3X+4}\)
\(8x^2+\sqrt{3x^2+6x+5}=74-\sqrt{36x-5}\)
