Question

35 chia hết x+1

 

Answer 1

\(\Rightarrow x+1\inƯ\left(35\right)=\left\{-35;-7;-5;-1;1;5;7;35\right\}\\ \Rightarrow x\in\left\{-36;-8;-6;-2;0;4;6;34\right\}\)

Answer 2

\(35⋮x+1\)

\(\Rightarrow x+1\in U\left(35\right)\)

\(\Rightarrow U\left(35\right)=\left\{\pm1;\pm5;\pm7\right\}\)

\(\Rightarrow x+1=\left\{2;4;5;34;0;-4;-6;-34\right\}\)
