Nếu p = 2 

=> p + 4 = 6 (loại) 

Nếu p = 3

=> p + 4 = 7 (tm)

=> p + 14 = 17 (tm)

Nếu p > 3

=> \(\orbr{\begin{cases}p=3k+1\\p=3k+2\end{cases}}\)

Khi p = 3k + 1 

=> p + 14 = 3k + 1 + 14 = 3k + 15 = 3(k + 5) \(⋮\)3 

=> p + 14 là hợp số (loại)

Khi p = 3k + 2

=> p + 4 = 3k + 2 + 4 = 3k + 6 = 3(k + 2) \(⋮\)3 (loại)

=> p + 4 là hợp số (loại)

Vậy p = 3

\(fx-f(x-1)=x \)

\(f=x\)

\(f-x=0\)

\(-(x-f)=0\)

\(x-f=0\)
