Description
This is the second in the Year 9 Algebraic Techniques series looking at binomial expansion and factorisation. This video takes time to look at the difference of perfect squares and which binomial products lead to the difference of perfect squares (DOPS) and which do not. I take time to explain things clearly and use lots and lots of worked examples. There might even be some humour thrown in!
