GPT: x4 - 6x + 1 = 2(x + 4)\(\sqrt{2x^3+8x^2+6x+1}\)
gpt \(x^{11}+3x^{10}+x^9+3x^8+x^7-3x^6-17x^5+3x^4+x^3+3x^2+x+3=0\)
GPT \(x^2+3x-\frac{7}{4}=2\sqrt{2x-3}\)
GPT: \(2x^2+\left(14-2\sqrt{x^2+8x}\right)x+8x-14\sqrt{x^2+8x}+24=0\)
Gpt \(\sqrt{1-x}\left(x-3x^2\right)=x^3-3x^2+2x+6\)
tính giá trị của p:
\(3x^5+12x^4-8x^3-23x^2-7x+1khix=-2+\sqrt{5}\)
lm nhanh giúp mk nhé!thanks
1)
a) gpt \(\sqrt{5-3x}+\sqrt{x+1}=\sqrt{3x^2-4x+4}\)
b) ghpt \(\left\{{}\begin{matrix}2xy+4x+3y+6=0\\4x^2+y^2+12x+4y+9=0\end{matrix}\right.\)
gpt:
\(\sqrt[3]{x-4}+\sqrt{x+4}=4\)
2)
a) gpt \(x^3+5x^2+10x=\left(3x^2+3x+6\right)\sqrt{x+2}\)
b)tìm nghiệm nguyên dương :\(x^2-y^2+x^2y-xy=x+14\)
