Giải pt:
\(\sqrt{x^2+x+4}+\sqrt{x^2+x+1}=\sqrt{2x^2+2x+9}\)
GIẢI PT 1) \(\sqrt[3]{x+1}\) -\(\sqrt{4-x}\)- x2 + 5x + 1 = 0
2) \(\sqrt{2x^2+11x+15}+\sqrt{x^2+2x-3}=x+6\)
Giải PT : \(x^2+\sqrt{2x+1}+\sqrt{x-3}=5x\left(1\right)\)
giai pt sau
\(\sqrt{3x-1}-\sqrt{x+2}.\sqrt{3x^2+7x+2}+4=4x-2\)
\(x^2-5x+3.\sqrt{2x-1}=2.\sqrt{14-2x}+5\)
\(\left(x+1\right)\left(x+4\right)-3\sqrt{x^2+5x+2}=6\)
Giải PT sau
a, \(\sqrt{2x+3}\)+\(\sqrt{x+1}\)=3x+\(\sqrt{2x^2+5x+3}\)-16
b, x^4 +\(\sqrt{x^2+2014}\)=2014
giải pt :
\(\sqrt{2x+3}+\sqrt{x+1}=3x+2\sqrt{2x^2+5x+3}-16\)
