Giải PT: \(\sqrt{\left(x^2+2x\right)^2+4\left(x+1\right)^2}-\sqrt{x^2+\left(x+1\right)^2+\left(x^2+x\right)^2}=2019\)
Giải PT: \(\sqrt{x-1}+\sqrt{x+3}+2\sqrt{\left(x-1\right).\left(x^2-3x+5\right)}=4-2x\)
1\(\left\{{}\begin{matrix}xy\left(x+y\right)=2\\x^3+y^3+x^3y^3+7\left(x+1\right)\left(y+1\right)=31\end{matrix}\right.\)
2 giải pt \(9+3\sqrt{x\left(3-2x\right)}=7\sqrt{x}+5\sqrt{3-2x}\)
Giải PT: \(\left(x+1\right).\sqrt{2x^2-2x}=2x^2-3x-2\)
Giải PT: \(\sqrt{x+5}+\sqrt{3-x}-2.\left(\sqrt{15-2x-x^2}+1\right)=0\)
Giải Pt:
\(\left(4x-1\right)\sqrt{x^2+1}=2x^2-2x+2\)
Em cảm ơn ạ.
Giải pt sau:
a. \(\sqrt{2x^2-3x-11}=\sqrt{x^2-1}\)
b. \(\sqrt{2x^2+3x-5}=x+1\)
c. \(\sqrt{\left(x+2\right)^2}=\sqrt{3x^2-5x+14}\)
d. \(\sqrt{\left(x-1\right)\cdot\left(2x-3\right)}=-x-9\)
giải pt: a) \(\sqrt{x+1}+\sqrt{5x}=\sqrt{4x-3}+\sqrt{2x+4}\)
b) \(\left(x-1\right)\left(x+2\right)+2\sqrt[]{x^2+x+1}=0\)
Giải PT và HPT
a) \(\sqrt{10x+1}+\sqrt{3x-5}=\sqrt{9x+4}+\sqrt{2x-2}\)
b) \(\left\{{}\begin{matrix}x^2-5y^2-8y=3\\\left(2x+4y-1\right)\sqrt{2x-y-1}=\left(4x-2y-3\right)\sqrt{x+2y}\end{matrix}\right.\)
