\(\sqrt{\frac{42}{5-x}}+\sqrt{\frac{60}{7-x}}=6\)
Giải phương trình
\(\sqrt{\frac{42}{5-x}}+\sqrt{\frac{60}{7-x}}=6\)
Giải Phương Trình :
\(\sqrt{\frac{42}{5-x}}\)+\(\sqrt{\frac{60}{7-x}}\)=6
ae gải hộ mk cái: giải phương trình
1: \(\sqrt{2x^2+x+6}+\sqrt{x^2+x+2}=\frac{x^2+4}{x}\)
2: \(\sqrt{x+3}-\sqrt{1-x}=1+x\)
3: \(\sqrt{x-2}+\sqrt{4-x}=2x^2-5x-1\)
4:\(\sqrt{x^2-x+1}-\sqrt{x^2+x+1}=2x\)
5:\(\sqrt{3x^2-7x+3}-\sqrt{x^2-2}=\sqrt{3x^2-5x-1}\)
6:\(\sqrt{\frac{42}{5-x}}+\sqrt{\frac{60}{7-x}}=6\)
7:\(\sqrt{x+\frac{3}{x}}=\frac{x^2+7}{2\left(x+1\right)}\)
gpt \(\sqrt{x^2+3x}+2\sqrt{x+2}=2x+\sqrt{x+\frac{6}{x}}+5\)
gpt \(\sqrt{\frac{x}{3}-3}+\sqrt{7-\frac{x}{3}}=2x-7-\frac{x^2}{9}\)
GPT: \(x^2-\frac{\sqrt{5}}{\sqrt{5}-2}\cdot x-\left(6-2\sqrt{5}\right)=0\)
GPT \(\frac{4}{X}+\sqrt{X-\frac{1}{X}}=X+\sqrt{2X-\frac{5}{X}}\)
1)\(7\sqrt{3x-7}+\left(4x-7\right)\sqrt{7-x}=32\)
2)\(4x^2-11x+6=\left(x-1\right)\sqrt{2x^2-6x+6}\)
3)\(9+3\sqrt{x\left(3-2x\right)}=7\sqrt{x}+5\sqrt{3-2x}\)
4)\(\sqrt{2x^2+4x+7}=x^4+4x^3+3x^2-2x-7\)
5)\(\frac{6-2x}{\sqrt{5-x}}+\frac{6+2x}{\sqrt{5+x}}=\frac{8}{3}\)
6)\(2\left(5x-3\right)\sqrt{x+1}+\left(x+1\right)\sqrt{3-x}=3\left(5x+1\right)\)
7)\(\sqrt{7x+7}+\sqrt{7x-6}+2\sqrt{49x^2+7x-42}=181-14x\)
