    Excellent. Will you be doing proof by induction, that was always a tough one for me.

      Thank you! Not yet, contradiction is coming next... focusing on the basic core syllabus for now. Love proof by induction though, so clever and powerful!

    Hi, love your videos! You really help me understand concepts which as a self student I sometimes find difficult!! :)
    On the last example, could explain how you completed the square? When I expand (x-y)^2 I get the original expression but I'm struggling to understand why half of 2xy is just y. I'd really appreciate your help with this. Thank you for your videos they're awesome!

      Hiya, that's lovely to hear! When you complete the square, take the x term and half the stuff that's around the x. So if you had 8x as the middle term, you would use 4. Here we have 2yx, so we use y. Hope that makes sense. Bes of luck!
