Gpt: \(2x+2\sqrt{x^2+5x}+\sqrt{x+5}+\sqrt{x}=25\)
gpt:
\(x^4-2x^3+x=\sqrt{(x^2-x).2}\)
\(x(5x^3+2)-2(\sqrt{2x+1}-1)=0\)
\(\sqrt{x+\frac{3}{x}}=\frac{x^2-7}{2x+2}\)
GPT : a, \(\sqrt{x^2-2x+5}\) + \(2\sqrt{4x+5}\)= \(x^3\)-\(2x^2\)+ \(5x+4\)
b,\(2x^2-5x-1=\sqrt{x-2}+\sqrt{4-x}\)
giúp mk vs : gpt :
A= \(\sqrt{x^2-2x+5}+2\sqrt{4x+5}=x^3-2x^2+5x+4\)
gpt:\(\sqrt{3x^2+6x+4}+\sqrt{2x^2+4x+11}=\left(1-x\right)\left(x+3\right)\)
\(\sqrt{3x^2+6x+7}+\sqrt{5x^2+10x+21}=5-x^2-2x\)
\(\sqrt{x^2-x+2}+\sqrt{x^2-3x+6}=2x\)
GPT :
\(x^3-4x^2+5x-1-\sqrt{2x-3}=0\)
gpt \(\sqrt{5x^3-1}+\sqrt[3]{2x-1}+x-4=0\)
GPT: \(\sqrt{2x+3-\sqrt{x+2}}+\sqrt{2x+4+\sqrt{x+2}}=1+2\sqrt{x+2}\)
Gpt \(2\left(2x^2+2x+1\right)=\left(5x+2\right)\sqrt{x^2+1}\)
