giai phuong trinh
giai phuong trinh:
\(\left(\sqrt{x+4}-2\right)\left(\sqrt{4-x}+2\right)=2x\)
giai phuong trinh \(\sqrt[4]{x+1}+\sqrt[4]{1-x}+\sqrt[4]{1-x^2}=3\)
giai phuong trinh
a) \(\sqrt{3x^2-7x+3}-\sqrt{x^2-2}=\sqrt{3x^2-5x-1}-\sqrt{x^2-3x+4}\)
b) x2 - 25 = y ( y + 6 ) (x; y nguyên)
Giai phuong trinh:
\(28+\sqrt[3]{x^2}=3x+2\sqrt[3]{x}+\left(x-4\right)\sqrt{x-7}\)
Giai phuong trinh: x2 - 10x + 27= \(\sqrt{6-x}+\sqrt{x-4}\)
Giai phuong trinh:
\(x+y+z-6046=2\sqrt{x-2019}+4\sqrt{x-2020}+6\sqrt{x-2021}\)
Giai phuong trinh sau: \(\sqrt{x}-\sqrt{x+1}-\sqrt{x+4}+\sqrt{x+9}=0\)
