GPT:
1/ \(\sqrt{7x^2+20x-86}+x\sqrt{31-4x-x^2}=x+1\)
2/ \(\sqrt[3]{\frac{12x^2+12x+9}{4}}=x+\sqrt[4]{\frac{4x^3-2}{3}}\)
Gpt: \(\sqrt{4x^2-4x+5}+\sqrt{12x^2-12x+19}=5+4x-4x^2\)
gpt: \(2\sqrt{3x+7}-5\sqrt[3]{x-6}=4\)
\(\left(x^2-3x+2\right)\left(x^2-12x+32\right)\le4x^2\)
\(\left(\sqrt{x+1}-1\right)\left(\sqrt{x^2-4x+7}+1\right)=x\)
GPT nè :\(\sqrt{7-x}+\sqrt{5-x}=x^2-12x+38\)
GPT : \(\sqrt[3]{x+3}+\sqrt[3]{5-x}=2\)
GPT :\(\left(\sqrt{5-x}\right)^3+\left(\sqrt{x-3}\right)^3=2\sqrt{2}\)
Gpt: \(\sqrt{x+5}+\sqrt{3-x}-2\left(\sqrt{15-2x-x^2}+1\right)=0\)
Giải phương trình
\(2x^3-\sqrt{108x+45}=x\sqrt{48x+20}-3x^2\)
Gpt: \(1+\dfrac{1}{\sqrt{x^2-1}}=\dfrac{35}{12x}\)
