giải pt \(x^3-3x^2+2\sqrt{x+3}^3-9x=0\)
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 \(\sqrt{3x^2-5x+1}-\sqrt{x^2-2}=\sqrt{3x^2-3x+3}-\sqrt{x^2-3x+4}\)
giải pt :
a) x3+1 = 2\(\sqrt[3]{2x-1}\)
b) x2-3x+1 = \(\frac{-\sqrt{3}}{3}\sqrt{x^4+4x^2+1}\)
\(x^3-3x^2+4x+1=\sqrt{3x+1}+\sqrt{3x^2+7x}\)
giúp mình với mình cần gấp sắp kt
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:
\(3x^2+2x+3=\left(3x+1\right)\sqrt{x^2+3}\) \(x^2+3x+4=\left(x+3\right)\sqrt{x^2+x+2}\)
\(\left(4x-1\right)\sqrt{x^2+1}=2x^2+2x+1\) \(15x^2+2\left(x+1\right)\sqrt{x+2}=2-5x\)
giải pt
\(\sqrt{2x-1}\) + x\(^2\)-3x +1=0
Giải PT: \(\sqrt{3x-2}-\sqrt{x+1}=2x^2-x-3\)
