for example:
\[\Large \begin{gathered}
2{x^4}\left( {2{x^2} + 3x + 4} \right) = \hfill \\
= \left( {2{x^4} \cdot 2{x^2}} \right) + \left( {2{x^4} \cdot 3x} \right) + \left( {2{x^4} \cdot 4} \right) = ...? \hfill \\
\end{gathered} \]

Answer 8

ohh okay so is it A

Answer 9

= \left( {2{x^4} \cdot 2{x^2}} \right) + \left( {2{x^4} \cdot 3x} \right) + \left( {2{x^4} \cdot 4} \right) = \hfill \\
= 4{x^6} + ...? \hfill \\
