The Islamic Golden Age of Science is largely to thank for our scientific developments today. Around 750-1250 CE, the Islamic empire made incredible scientific advancements that changed the course of history! Join Michael Aranda for a...

You know the Golden Ratio, but what is the Silver Ratio?

In which Hank shows you that, while it may seem like the Universe is messing with us, equilibrium isn't a cosmic trick. Here, he shows you how to calculate equilibrium constant & conditions of reactions and use RICE tables all with...

New ReviewIn this short math lesson, we’ll solve a quadratic equation step-by-step using completing the square. We follow 6 quick steps: 1️⃣ If necessary, “move” c to the right side of the equation. 2️⃣ If necessary, divide all terms by a. 3️⃣...

New ReviewLet's master how to solve quadratic equations in some easy to understand steps. In this video we will cover the square root method, factoring out the GCF, factoring trinomials and using the quadratic formula.

New ReviewWhile this may look like two linear equations we are actually working with a linear equation and a reciprocal equation.

New ReviewIn this video we are going to explore how to graph a quadratic equation using vertex form using a easy, medium and hard example.

New ReviewLet's tackle how to factor a quadratic like this one. When you have a fraction as the middle term there are some things you need to know.

New ReviewUsually I recommend that students solve simultaneous equations using substitution when an equation is not linear but in this example you can actually using substitution or elimination.

New ReviewIn this video we are going to explore how to solve rational equations given an easy example and a more difficult example with extraneous solutions.

New ReviewIn this video I am going to go over the three rules of the quadratic formula that you need to know. It's not just about plug and chug. There is so much more to it.

In this shorts math video we will learn how to solve a quadratic equation two ways to answer a standardized math test question. We will be presented with an equation and four answer choices. We will understand that x squared is...
