BCA4.1.1. Polynomial Example: Subtraction with Parentheses

I'd just like you to know I'm extremely grateful for your sharing of these college level mathematics videos .... I've watched your videos (although not fully understanding them) for quite some time now ... I think the last time I commented on one was saying something about feeling lost with maths BUT these recent videos you have been posting really have made me feel so much better about approaching things. - Thank you sooooo much!

I like the calculus stuff, the lectures on the Laplas transform were particularly helpful.

Thanks! The LT sequence was great fun to shoot.
