\(\sqrt{2x-2}+\sqrt[3]{x-2}=\dfrac{9-x}{\sqrt[3]{8x-16}}\)

Tìm min:

\(M=4\left(a+b+c\right)^2+3\left(\dfrac{1}{a}+\dfrac{1}{b}+\dfrac{1}{c}\right)\) \(với\) \(a,b,c>0\)

\(Cho\) \(a,b,c>0\) \(và\) \(abc=1\)

\(CMR:\) \(\dfrac{a}{a^3+a+1}+\dfrac{b}{b^3+b+1}+\dfrac{c}{c^3+c+1}\le1\)

\(x^2+10x-24\)

\(=x^2-2x+12x-24\)

\(=x\left(x-2\right)+12\left(x-2\right)\)

\(=\left(x-2\right)\left(x+12\right)\)
