[Lấp La Lấp Lánh]

a) \(\Rightarrow\left(n+2\right)+3⋮\left(n+2\right)\)

\(\Rightarrow\left(n+2\right)\inƯ\left(3\right)=\left\{-3;-1;1;3\right\}\)

\(\Rightarrow n\in\left\{-5;-3;-1;1\right\}\)

b) \(\Rightarrow\left(n+1\right)+6⋮\left(n+1\right)\)

\(\Rightarrow\left(n+1\right)\inƯ\left(6\right)=\left\{-6;-3;-2;-1;1;2;3;6\right\}\)

\(\Rightarrow n\in\left\{-7;-4;-3;-2;0;1;2;5\right\}\)

c) \(\Rightarrow\left(n+1\right)^2-\left(n+1\right)+13⋮\left(n+1\right)\)

\(\Rightarrow\left(n+1\right)\inƯ\left(13\right)=\left\{-13;-1;1;13\right\}\)

\(\Rightarrow n\in\left\{-14;-2;0;12\right\}\)

d) \(\Rightarrow\left(n+2\right)^2-\left(n+2\right)+7⋮\left(n+2\right)\)

\(\Rightarrow\left(n+2\right)\inƯ\left(7\right)=\left\{-7;-1;1;7\right\}\)

\(\Rightarrow n\in\left\{-9;-3;-1;5\right\}\)
