giai pt:
a) \(\sqrt{x^2-4x-12}=9-2x\)
b) \(\left(x+1\right)\sqrt[3]{15x^2-x-1}=x^2-1\)
c) \(\left(2x-2\right)\sqrt{2x-1}=6\left(x-1\right)\)
d) \(\frac{\sqrt{-x^2+4x-3}-1}{x-3}=2\)
e) \(\frac{5+\sqrt{x+1}}{x-2}=7\)
giai pt: \(4\sqrt{2x-1}\)= x^2+10x-4
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 : 2$\sqrt{x+1}$ - $\sqrt{2x-5}$ = 6 - x
Giải giúp mik mấy bài pt vô tỉ vs ak!
1)\(x=\sqrt{5-x}\sqrt{6-x}+\sqrt{6-x}\sqrt{7-x}+\sqrt{7-x}\sqrt{5-x}\)
2)\(2x-1=\sqrt{2-x}\sqrt{10-4x}+\sqrt{5-2x}\sqrt{6-2x}+2\sqrt{3-x}\sqrt{2-x}\)
Giải pt :
\(\sqrt{x^2-2x+5}+\sqrt{x-1}=2\)
Giai pt \(\left(x+5\right)\sqrt{x+1}+1=\sqrt[3]{3x+4}\)
