$\begin{gathered}\qquad:\implies \sf \: x^3 + 27x^2 + 243x + 631 \:\:\\\\ \\ \qquad:\implies \sf \: (2)^3 + 27(2)^2 + 243(2) + 631 \:\:\\\\\\ \qquad:\implies \sf \: 8 + 27(2)^2 + 243(2) + 631 \:\:\\\\\\ \qquad:\implies \sf \: 8 + 27(4) + 243(2) + 631 \:\:\\\\ \\ \qquad:\implies \sf \: 8 + 108 + 243(2) + 631 \:\:\\\\\\ \qquad:\implies \sf \: 8 + 108 + 486 + 631 \:\:\\\\\\ \qquad:\implies \sf \: 116 + 486 + 631 \:\:\\\\\\\qquad:\implies \sf \: 602 + 631 \:\:\\\\\\ \qquad:\implies \sf \: 1233 \:\:\\\\\\ \qquad:\implies \underline {\boxed {\pmb{\bold{ \: x^3 + 27x^2 + 243x + 631 \:\:=\:\:1233 \:\:}}}}\:\:\bigstar \:\:\\\\\end{gathered}$
