## How to Solve Quadratic Equations

Following up my previous post that gave you advice on how to solve equations, in this post I would like to go over some strategies on how to solve quadratic equations. Quadratic equations become very common in high school math and college math, and they require a bit more work sometimes to solve. You may…

## Using the Quadratic Formula

So, now that you know the answer to ‘What is the Quadratic Formula’ next I will show you examples of using it. Refer back to my last post to familiarize yourself with what the quadratic formula looks like. I’ve also explained there the nature of the roots of a quadratic equation. If you haven’t read…

## The Quadratic Formula

Following my posts on How to Solve Quadratic Equations, you will soon find that not all quadratic equations can be solved by quadratic factoring, and you will come to rely on The Quadratic Formula to help you. As a quick refresher, a quadratic equation is one which takes the form of ax2 + bx +…

## Guide on How to Solve Equations

Knowing how to solve equations is a very important skill to have in mathematics courses. There are all kinds of manipulations and substitutions that could be possible for any given equation, but knowing where and when to apply certain techniques is crucial to solving rational equations correctly. In this post, I am going to go…

## Methods of Factoring

For this post, I would like to do one that talks about various methods of factoring which you can use to find factors. There are several different factoring techniques that you can use, depending on the situation, so I think that I would like to include a variety of methods or factoring tricks. First of…

## The Merry Christmas Equation

This is a fun post for the holiday season that I first read over at my friend Guillermo’s page, Math and Multimedia. You often hear that everything can be described by mathematics. In this case, we’re going to use some math to convey a special message for this time of year! To begin, let’s start…

## Google’s Free Online Calculator

It’s probably happened to you before: you go to do your math homework and you suddenly realize that you don’t have your calculator handy. What if you have a test tomorrow and you absolutely need your calculator right now to help you study? If you have your smartphone or computer with you, you can easily…

## Multiplying Integers – Why Multiplying Two Negatives is a Positive

I have recently been asked to explain why two negative numbers multiply together to product a positive number. This can be a difficult concept to grasp at first, but I would like to try to simplify an explanation. First, I would like to recommend and give credit to David’s website, at Practic-All. In particular, he…

## What are Real Numbers? Rational, Irrational, Natural, and Integer Numbers

What are Real Numbers? When you are first learning to do math with numbers, you never think about what “kinds” of numbers you use. You just add 2 plus 2, or subtract 10 from 20, and later on begin to multiply (-3) times (-5) and other, more complicated functions. What you don’t even realize is…
