Giải pt :
\(\left\{{}\begin{matrix}6\frac{x}{y}-2=\sqrt{3x-y}+3y\\2\sqrt{3x+\sqrt{3x-y}}=6x+3y-4\end{matrix}\right.\)
giải pt
\(2\left(x+1\right)\sqrt{x}+\sqrt{3\left(2x^3+5x^2+4x+1\right)}=5x^3-3x^2+8\)
giải pt sau: 3x2 +2|x+1|=3
giải pt : \(\frac{4}{x-2}+x=\frac{3x-2}{x-2}\)
Giải pt :
\(\left\{{}\begin{matrix}3x^2+2xy+2y^2-3x-2y=0\\5x^2+2xy+5y^2-3x-3y-2=0\end{matrix}\right.\)
\(\sqrt{\left(x-3\right)^2\left(5-3x\right)}+2x=\sqrt{3x-5}+4\)
\(5x^4-2x^2-3x^2\sqrt{x^2+2}=4\)
(3x-1)^2-6(x-1)(x+1)-3x(x-2)=7
tìm x giúp mik
giair hpt: (3x+\(\sqrt{1+9x^2}\)).(y+\(\sqrt{1+y^2}\))=1
và x^2+y^2-4x+8y-9=0
