\(\Leftrightarrow\) Với mọi \(x>0\) ta luôn có:
\(x^3-x^2-2x+m\left(x+1\right)\ge0\)
\(\Leftrightarrow\left(x+1\right)\left(x^2-2x\right)+m\left(x+1\right)\ge0\)
\(\Leftrightarrow\left(x+1\right)\left(x^2-2x+m\right)\ge0\)
\(\Leftrightarrow x^2-2x+m\ge0\) (do \(x+1>0\) ; \(\forall x>0\))
\(\Leftrightarrow m\ge-x^2+2x\)
\(\Leftrightarrow m\ge\max\limits_{x>0}\left(-x^2+2x\right)=1\)
\(\Rightarrow m=\left\{1;2;3;4;...;10\right\}\)
