Giải pt
\(\sqrt[3]{x^2+3x+3}+\sqrt[3]{2x^2+3x+2}=6x^2+12x+8\)
Giải pt
\(\sqrt[3]{x^2+3x+3}+\sqrt[3]{2x^2+3x+2}=6x^2+12x+8\)
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) \(\sqrt{1+x}+\sqrt{1-x}+\frac{x^2}{4}=2\)
