giải pt: \(\sqrt{3x^2-5x+1}-\sqrt{x^2-2}=\sqrt{3\left(x^2-x-1\right)}-\sqrt{x^2-3x+4}\)
giải pt
\(3\left(x+\sqrt{x^2+1}\right)=-3x^2-2\sqrt{3}x+3\sqrt{3}-1\)
Giải pt: \(3\left(x+2x\sqrt{x^2+1}\right)=-3x^2-2x\sqrt{3}+3\sqrt{3}-1\)
giải pt:
1) \(4\sqrt{\frac{x^2}{3}+4}=1+\frac{3x}{2}+\sqrt{6x}\)
2) \(3\left(\sqrt{2x^2+1}-1\right)=x\left(1+3x+8\sqrt{2x^2+1}\right)\)
3) \(\sqrt{1+x}+\sqrt{1-x}+\frac{x^2}{4}=2\)
Giải pt \(x\:+\sqrt{x}+1+\left(2\sqrt{5}-1\right)\sqrt{x}=3x-2\sqrt{x-4}+3 \)
Giải pt: \(\sqrt{1+\sqrt{1-x^2}}=\left[\left(\sqrt{1+x}\right)^3-\left(\sqrt{1-x}\right)^3\right]=2+\sqrt{1-x^2}\)
Giải PT: \(\sqrt{x-1}+\sqrt{x+3}+2\sqrt{\left(x-1\right)\left(x^2-3x+5\right)}=4-2x\)
