bài đấy để mk nghĩ đã giờ mk đi ngủ rồi
<=>\(\sqrt{x^3+1}=\sqrt{\left(x+1\right)\left(x^2-x+1\right)}\)
\(\Rightarrow\sqrt{x^3+1}=2x^2-3x+1\)
=>x=0 hoặc 2
giải pt: \(11\sqrt{5-x}+8\sqrt{2x-1}=24+3\sqrt{\left(5-x\right)\left(2x-1\right)}\)
giải pt
\(\frac{2\left(x-\sqrt{2}\right)\left(x-\sqrt{3}\right)}{\left(1-\sqrt{2}\right)\left(1-\sqrt{3}\right)}+\frac{3\left(x-1\right)\left(x-\sqrt{3}\right)}{\left(\sqrt{2}-1\right)\left(\sqrt{2}-\sqrt{3}\right)}+\frac{4\left(x-1\right)\left(x-\sqrt{2}\right)}{\left(\sqrt{3}-1\right)\left(\sqrt{3}-2\right)}\)=3x-1
Giải PT: \(\sqrt{x-1}+\sqrt{x+3}+2\sqrt{\left(x-1\right)\left(x^2-3x+5\right)}=4-2x\)
Giải pt
\(x^2+6x+1=\left(2x+1\right)\sqrt{x^2+2x+3}\)
Giải pt: \(\sqrt{x^3+1}=\left(x-1\right)\left(2x-1\right)\)
Giải PT: \(2\left(x-1\right)^2=3\left(\sqrt{x^3+2x^2-2x+3}+2\right)\)
Giải Pt :
\(\sqrt{x-1}+\sqrt{x+3}+2\sqrt{\left(x-1\right)\left(x^2-3x+5\right)}=4-2x\)
Giải pt:
a)\(\sqrt{x+2}+\sqrt{x-2}+2\sqrt{x^2-4}=6-2x\)
b)\(\left(\sqrt{x+3}-\sqrt{x}\right)\left(\sqrt{1-x}+1\right)=1\)
c)\(\left(\sqrt{1+x}+\sqrt{1-x}\right)\left(2+2\sqrt{1-x^2}\right)=8\)
giải pt : \(\sqrt{\left(x+1\right)\left(2-x\right)}=1+2x-2x^2\)
