**You might be used to the Quadratic Formula if you're familiar with the Secondary School Maths curriculum. It's a very simple equation that spits out the answers you want as long as you put the coefficients in the right parts of the equation.**

** **

**It's also one of the first times you were given a mathematical formula featuring such complex algebraic arrangements & for most of you, realise how useful algebra is - Just find out what those numbers before your x^2 and x are, pop them in and you'll get the answer 'magically'.**

**There is a more complex iteration known as the cubic formula, which isn't taught early on in the curriculum that is also really useful for solving cubic equations. This video will give you a thorough understanding of the formula's machinations and how every part of the equation contributes to the graph in a meaningful way.**
