nghiệm có nguyên k bn???
GPT: \(\sqrt{x^2+x-1}\sqrt{x^2-x+1}=x^2-x+2\)
GPT : \(\sqrt{x-2}-\sqrt{x+1}=\sqrt{2x-1}-\sqrt{x+3}\)
\(\left(\sqrt{x+1}-\sqrt{x-2}\right)\left(1+\sqrt{x^2-x-2}\right)\)=3
gpt
GPT : \(\sqrt[3]{2-x}+\sqrt{x-1}=1\)
\(\sqrt{1-x}+\sqrt{1+x}+2\sqrt{1-x^2}=4\) gpt giúp mình nha
GPT:
\(\left(\sqrt{x+3}-\sqrt{x-2}\right)\left(1+\sqrt{x^2+x-6}\right)=5\)
Help me!
Gpt:
a.\(\sqrt{x-1}-\sqrt{5x-1}=\sqrt{3x-2}\)
b. \(\sqrt{x-2}-3\sqrt{x^2-4}=0\)
GPT : \(x^2+1+4x=\left(x+4\right)\sqrt{x^2+1}\)
Gpt: \(x-4\sqrt{2x+4}-2\sqrt{1-x}+9=0\)
