giải pt \(\sqrt{x-2}+\sqrt{4-x}+\sqrt{2x-5}=2x^2-5x\)
2) \(x^2+x+2=\sqrt{5x+5}+\sqrt{3x+2}\)
giải pt
a) \(x+\sqrt{x+8}\left(1-\sqrt{x+8}\right)=\sqrt{x}+\sqrt{x+3}-8\)
b) \(2\left(2-x\right)=\sqrt{2x-4}\left(\sqrt{5-x}-\sqrt{3x-3}\right)\)
c) \(\sqrt[3]{24+x}.\sqrt{12-x}-6\sqrt{12-x}=x-12\)
d) \(\frac{x-1}{2\sqrt{3-2x}-3}=\frac{x-1}{3-2\sqrt[3]{5+3x}}\)
Giải pt
a) \(2\sqrt[3]{x^2+5x-2}=x\left(x+5\right)+2\)
b) \(3x^2-12x-5\sqrt{10+4x-x^2}+12=0\)
c) \(\left(x+5\right)\left(2-x\right)=3\sqrt{x^2+3x}\)
d) \(\sqrt{3-x+x^2}-\sqrt{2+x-x^2=1}\)
e) \(\sqrt{x^2-3x+3}+\sqrt{x^2-3x+6}=3\)
giải pt:
a. \(\sqrt{x-2}+\sqrt{10-x}=x^2-12x+40\)
b. \(\sqrt{3x-5}+\sqrt{7-3x}=5x^2-20x+22\)
c. \(\sqrt{x^2-4x+4}+\sqrt{x^2-6x+9}=1\)
Mn ơi giải giúp mình pt này vs :
\(19+3x+4\sqrt{-x^2-x-6}=6\sqrt{2-x}+12\sqrt{2-x}+12\sqrt{x+3}\)
Giải phương trình sau:
\(\sqrt{x^2+12}+5=3x+\sqrt{x^2+5}\)
Giải pt sau:
\(1+\sqrt{x^2-4x+3}-x=0\)
\(\sqrt{x+1}=3-\sqrt{x-4}\)
\(\sqrt{x+1}-\sqrt{x-7}=\sqrt{12-x}\)
\(x-\sqrt{2x^2+3x-5}=2x-1\)
Cần gắp mn oii
giải pt
a) \(\sqrt{x^2+x+1}+\sqrt{3x^2+3x+2}=\sqrt{5x^2+5x-1}\)
b) \(\sqrt{x^2+x+4}+\sqrt{x^2+x+1}=\sqrt{2x^2+2x+9}\)
c) \(\sqrt{3x^2-5x+7}+\sqrt{3x^2-7x+2}=3\)
d) \(\sqrt{x^2+3x+2}=\sqrt{2x^2+9x+7}-\sqrt{x^2+6x+5}\)
giải pt
a) \(\frac{3-2\sqrt{x^2+3x+2}}{1-2\sqrt{x^2-x+1}}=1\)
b) \(\sqrt{3x^2-5x+7}+\sqrt{3x^2-7x+2}=3\)
c) \(\sqrt{x^2+3x+2}+\sqrt{x^2+6x+5}=\sqrt{2x^2+9x+7}\)
d) \(\sqrt{x^2-1}-\sqrt{x^2+3}+\sqrt{5-x}=0\)
e) \(\left(x-1\right)\sqrt{1+x\sqrt{x^2+4}}=x^2-1\)
