So, we have learned how to complete the square, but did we learn much about why we are doing it? Well, a little bit!
In this video, I look at how we can solve quadratic equations by completing the square. I look at why we want to complete the square and what it means to solve an equation. In this video, we decide that solving means to make the value of y in each equation equal to zero.
Why? Well, this allows us to find the x-axis intercepts ... which is what we mean (at the moment) by solving an expression.
There are a number of worked examples and a smattering of jokes and humour. I really hope you enjoy it!
There are no current errors with this video ... phew!
