Completing the square is another way of solving quadratics (as well as by factorising and by using the quadratic formula).
Completing the square will always work, whatever the quadratic (whereas factorising does not always work). Completing the square also helps us when sketching the graph, as it provides us with the coordinates of the turning point (minimum or maximum).
In this video we look at the process we follow to complete the square.
We will then use completing the square to solve quadratics in part 2, and to sketch graphs in the third video on completing the square.

In this video, we are going to look at parallel lines. To find the equation of parallel lines, we still use the y=mx + c equation, and because they have the same gradient, we know straight away that the gradient ‘m’ will be the same. We then just need to find the missing y-intercept ‘c’ value.

Plants have developed responses called tropisms. A tropism is a growth in response to a stimulus; so light and water in the plant’s case.
There are different types of tropisms: Positive tropisms are when growth is towards the stimulus - so the plant growing towards the light to maximise the stimul
