Expand four multiplied by three plus nine 𝑥.

In order to expand a single bracket, we need to multiply the number outside the bracket by both of the numbers inside the bracket. Four multiplied by three is equal to 12. Therefore, our first term will be 12. Four multiplied by nine 𝑥 is equal to 36𝑥. Therefore, our second term is 36𝑥. The expansion of four multiplied by three plus nine 𝑥 is 12 plus 36𝑥.
