giải pt :
a) x3+1 = 2\(\sqrt[3]{2x-1}\)
b) x2-3x+1 = \(\frac{-\sqrt{3}}{3}\sqrt{x^4+4x^2+1}\)
Giai pt:
a, \(x^2+\sqrt[3]{x^4-x^2}=2x+1\)
b, \(x+1+\sqrt{x^2-4x+1}=3\sqrt{x}\)
c, \(\sqrt{2x^2+7x+10}+\sqrt{2x^2+x+4}=3\left(x+1\right)\)
d, \(2\left(x^2-3x+2\right)=3\sqrt{x^3+8}\)
Mong moi nguoi giup do, em can gap !!!
giải pt \(\sqrt{3x^2-5x+1}-\sqrt{x^2-2}=\sqrt{3x^2-3x+3}-\sqrt{x^2-3x+4}\)
Giải các phương trình sau:
1) \(\sqrt{3x^2+5x+8}-\sqrt{3x^2+5x+1}=1\)
2) \(x^2-2x-12+4\sqrt{\left(4-x\right)\left(2+x\right)}=0\)
3) \(3\sqrt{x}+\dfrac{3}{2\sqrt{x}}=2x+\dfrac{1}{2x}-7\)
4) \(\sqrt{x}-\dfrac{4}{\sqrt{x+2}}+\sqrt{x+2}=0\)
5)\(\left(x-7\right)\sqrt{\dfrac{x+3}{x-7}}=x+4\)
6) \(2\sqrt{x-4}+\sqrt{x-1}=\sqrt{2x-3}+\sqrt{4x-16}\)
7) \(\sqrt{x+2\sqrt{x-1}}+\sqrt{x-2\sqrt{x-1}}=\dfrac{x+3}{2}\)
