In my opinion one of the hardest to understand forms was the standard form. There are many things that were needed to be taken into account with the standard form. One in particular was the fact that standard form could be turned into vertex form and factored form following a couple of steps. These steps were difficult for me to understand at the start. But after some practice I was able to easily understand how the standard form correlated with the factored form and vertex form quadratic relations. By understanding this concept, it was very easy for me to understand how to graph a parabola. Being able to fully understand standard form allowed me to easily solve some of the recurring word problems such as the ones that involve completing the square of an equation to find the max height and time at which the max height was reached (a.k.a vertex).
