## Quadratic Factorisation — A General Method that Conquers Each and Every Quadratic Trinomial

When it comes to quadratic polynomials — which seem to come in all different *forms* and *sizes* — most of us have spent at least a semester just learning about how to maneuver around them.

Indeed, when we look through a standard pre-college math curriculum pertaining to **quadratic expressions**, we would stumble upon topics such as **Square of a Sum**, **Square of a Difference**, **Completing the Square**, **Direct Factoring**, **Grouping**, **Difference of Squares**. **AC method** (if you’re lucky) and **Quadratic Formula** — among others.

In what follows though, we will — in addition to putting some of these techniques into good use — develop a general technique for factorising *any* kind of quadratic polynomials. And yes — it would also include those with **complex numbers** as coefficients. 🙂 More
