 Proving the correctness of this statement constructively means to actually find some concrete field elements that satisfy the decision function $R_{3.fac}$, like $x_1= 2$, $x_2 =12$, $x_3=4$ and $x_4 = 5$. The string $<2,12,4,5>$ is therefore a constructive proof for the statement that $L_{3.fac}$ contains words, and the computation $R_{3.fac}(<2,12,4,5>)=true$ is a verification of that proof. In contrast, the string $<2, 12, 4, 7>$ is not a proof of the statement, since the check $R_{3.fac}(<2,12,4,7>)=false$ does not verify the proof.
