GPT :\(7\sqrt{x}-2x+13=0\)
GPT \(x^2+3x-\frac{7}{4}=2\sqrt{2x-3}\)
GPT: x4 - 6x + 1 = 2(x + 4)\(\sqrt{2x^3+8x^2+6x+1}\)
GPT
\(2x^2+x+\sqrt{x^2+3}+2x\sqrt{x^2+3}\)
gpt : \(\sqrt{\dfrac{x^2-2x+1}{x^2-6+9}}=0\)
GPT: \(2x^2+\left(14-2\sqrt{x^2+8x}\right)x+8x-14\sqrt{x^2+8x}+24=0\)
tìm x:
\(\sqrt{x^2+x+1}=1\)
\(\sqrt{x^2+1}=-3\)
\(\sqrt{x^2-10x+25}=7-2x\)
\(\sqrt{2x+5}=5\)
\(\sqrt{x^2-4x+4}-2x+5=0\)
\(x^4+2x^3-2x-5=0\)
giải phương trình
2x - 3* √(2x-1) -5 =0
X^2 + 4x + 5= 2*√(2x +3)
x^2 - 3x + 8= 4*√(3x-5)
