So what do we think of the factor theorem? Not as intimidating as you thought, you probably have been using it for years without realizing it.
Factor By Grouping: Hard to solve? No. Hard to remember? It can be, just remember to practice, practice practice! Also, if you are in need of a review of other methods of factoring quadratic equations, click this link here.

Equation of A Circle
Ahoy math friends and welcome to Math Sux! In this post, we are going to learn about the equation of a circle, mainly how to write it when given a circle on a coordinate plane. We’ll see how to find the radius and center from the graphed circle and then see how to transfer that into our equation of a circle. And we’re going to do all of this step by step with the following Regents question. Stay curious and happy calculating! 🙂
Let’s mark up this coordinate plane and take as much information away from it as possible. When looking at this coordinate plane, we can find the value of the circle’s center and the circle’s radius.
Now that found the center and radius, we can fit each into our equation:
The only equation that matches our center and radius, is choice (2).
If the above answer makes sense to you, that’s great! If you need a little further explanation, keep going!
Equation of a Circle: Let’s take a look at our answer and break down what each part means:
So what do you think of circles now? Not to shabby, ehh? 🙂

Howdy math peeps! In this post, we are going to go over the recursive formula step by step by reviewing a Regent’s question. Yes, it is the recursive formula jam, well at least it’s my kind of jam. These things may look weird, confusing, and like a “what am I doing?” moment, but trust me they are no so bad!
How do I answer this question?
At first glance, all of these answer choices may look exactly the same. The first thing I would want to do with this question is to identify how all of theses answer choices are different. Take a look below:
What is the Recursive Formula?
A Recursive Formula is a formula that forms a sequence based on the previous term value. All this means is that it uses a formula to form a sequence-based pattern.
Let’s go through each choice to identify the answer:
Our goal is to test out each choice given, until we get the desired sequence:

Ahoy math friends! In this post, we are going to focus on solving log equations by solving this Regents questions step by step. We’ll answer this question right away! But if you need more of a review, keep reading and you will find what logarithms are, the different kinds of logarithms rules, and some simpler examples. Ready for our first example?! Check it out below:
Step 1: Let’s re-write the equation to get rid of the “log.”
Step 2: Solve for x in our new equation (5x-1)(1/3)=4
If the above answer makes sense to you, great! If not, that’s ok too, keep reading for a review on solving log equations.
Logarithms are inverses of exponential equations. Take a look below for a clearer picture.
Logarithms can be re-written to get rid of the word “log.” This makes them easier to solve and understand.
There are a few rules you have to
memorize get used to with practice. These rules are used when solving for x in different kinds of algebraic log problems:
