I just watched this video for my brother's benefit but I'm yr 11 and we were looking at triple brackets and I didn't understand where all the extra terms for coming from as I was multiplying them by the first term in the bracket and then multiplying the already multiplied terms by the second term in the bracket. Thanks for clearing up my confusion!
