\(x^{50}+x^{49}+x^{48}+...+x^2+x+1\)
\(=\left(x^{50}+x^{49}+...+x^{34}\right)+\left(x^{33}+x^{32}+...+x^{17}\right)+\left(x^{16}+x^{15}+..+1\right)\)
\(=x^{34}\left(x^{16}+x^{15}+...+1\right)+x^{17}\left(x^{16}+x^{15}+...+1\right)+\left(x^{16}+x^{15}+...+1\right)\)
\(=\left(x^{46}+x^{45}+...+1\right)\left(x^{34}+x^{17}+1\right)\)
Vậy...
