Question

(a+1)^3, Need help multiplying this polynomial I am having a hard time with the 3rd

Answer 1

\[\large (a+1)^3 \quad = \quad (a+1)(a+1)(a+1)\]
Let's start by multiplying out just these two blue brackets.\[\large (a+1)\color{royalblue}{(a+1)(a+1)}\]Do you remember how to `FOIL` them out? :)
