giải pt
a) \(\sqrt{3x-2}-\sqrt{5-x}=\sqrt{2x-4}\)
b) 2(1-x)\(\sqrt{x^2+2x-1}\) = 4-2x
giải pt :
a) x3+1 = 2\(\sqrt[3]{2x-1}\)
b) x2-3x+1 = \(\frac{-\sqrt{3}}{3}\sqrt{x^4+4x^2+1}\)
Giải PT: \(\sqrt[3]{x+2}+\sqrt[3]{x+1}=\sqrt[3]{2x^2}+\sqrt[3]{2x^2+1}\)
giải pt
a) 2\(\sqrt[3]{x^2-4x-4}\) - 2\(\sqrt{x-1}\) +x+4 = 0
b) 2x3 + 3x2 - 17x - 26 = 2\(\sqrt{x+1}\)
Giải pt:
\(3x^2+2x+3=\left(3x+1\right)\sqrt{x^2+3}\) \(x^2+3x+4=\left(x+3\right)\sqrt{x^2+x+2}\)
\(\left(4x-1\right)\sqrt{x^2+1}=2x^2+2x+1\) \(15x^2+2\left(x+1\right)\sqrt{x+2}=2-5x\)
