giải phương trình sau:
a) \(4x^2+\left(8x-4\right).\sqrt{x}-1=3x+2\sqrt{2x^2+5x-3}\)
b) \(8x^3-36x^2+\left(1-3x\right)\sqrt{3x-2}-3\sqrt{3x-2}+63x-32=0\)
c) \(2\sqrt[3]{3x-2}-3\sqrt{6-5x}+16=0\)
d) \(\sqrt[3]{x+6}-2\sqrt{x-1}=4-x^2\)
giải các pt sau
x\(^2+5x+\sqrt{x^2+5x+4}=2\)
\(\left(x+5\right)\left(2-x\right)=3\sqrt{x^2+3x}\)
Giúp e giải pt:
2x-3+\(\frac{3x-1}{\sqrt{3-2x^2}+2-x}=0\)
\(^{x^2+4x+1=\left(x+4\right)\sqrt{x^2+1}}\)
\(2\left(x-2\right)\sqrt{x-1}=3x^2+5x-4-4x\sqrt{2x-1}\)
giai pt sau
\(\sqrt{3x-1}-\sqrt{x+2}.\sqrt{3x^2+7x+2}+4=4x-2\)
\(x^2-5x+3.\sqrt{2x-1}=2.\sqrt{14-2x}+5\)
\(\left(x+1\right)\left(x+4\right)-3\sqrt{x^2+5x+2}=6\)
Ai dậy r giúp vs :33 1 câu cx đc nhé :v toàn giải pt hết nhé
1) \(4x^2+\left(8x-4\right)\sqrt{x}-1=3x+2\sqrt{2x^2+5x-3}.\)
2) \(\left(5x+8\right)\sqrt{2x-1}+7x\sqrt{x+3}=9x+18-\left(x+26\right)\sqrt{x-1}\)
3) \(\sqrt[3]{3x+1}+\sqrt[3]{5-x}+\sqrt[3]{2x-9}-\sqrt[3]{4x-3}=0\)
4) \(\left(x+17\right)\sqrt{4-x}+\left(20-x\right)\sqrt{x+1}-9\sqrt{4-x}.\sqrt{x+1}=36\)
giải các pt vô tỉ sau:
1, \(x^2\)-\(5x\)+\(4\)=\(\left(2x-1\right)\sqrt{x^2-3x+4}\)
2, \(2\sqrt{\left(x+2\right)^3}=6x+3x^2-x^3\)
3, \(x=\left(\sqrt{x}+2\right)\left(1-\sqrt{1-\sqrt{x}}\right)^2\)
hộ e vs ak
Giải các pt vô tỉ sau ( bằng phương pháp đặt ẩn phụ đưa về phương trình tích )
a) \(\sqrt{x^3+x^2+3x+3}+\sqrt{2x}=\sqrt{x^2+3}+\sqrt{2x^2+2x}\)
b) \(\sqrt{x^2-3x}+2\sqrt{x}-4\sqrt{x-3}-x+8=0\)
c) \(\left(5x^2+4x+3\right)\sqrt{x}=\left(x+3\right)\sqrt{5x^2+4x}\)
d) \(\left(x+2\right)\sqrt{3x+\frac{1}{x}}=3x^2+3\)
e)\(\left(x^2+2x+1\right)3\sqrt{x^2+\frac{3}{x}}=x^3+2x^2+5\)
