Algebra 2

So one way to solve the system of linear equations in two variables is graphing by the two lines that are represented by the equations. And then any point where they touch is one of the solutions. So...

Okay, here let's talk about the factor theorem and look at a few examples. A polynomial F (X) has a factor of (X - K) if and only if F (K) = 0. What this says is that if you have a factor of...

This is the first of two videos where we learn about relational algebra. Relational Algebra is a formal language. It's an algebra that forms the underpinnings of implemented languages like...

The last operator that I'm going to cover in this video is the theta join operator. Like natural join, theta join is actually an abbreviation that doesn't add expressive power to the...

hi this is tracy from kuta software i'm going to demonstrate how easy it is to create an assignment using infinite algebra one here is a blank new assignment in the upper right is the list of...

Here’s an unshmoopy question you may find on an exam… What does 9 to the one-half power plus the square root of 4 equal? And here are the potential answers… Ooh. Cool problem. So this “to the half”...

Hi, I'm Kendall Roberg, and today we are going to perform operations on functions. We have 2 functions, f and g. f in terms of x is defined as -x + 4. g of x is 2x + x^2. So what would happen...

Simplify 3 times the square root of 200x to the third. So a good place to start, let's factor out 200. So if I'm just focusing on the 200 here, 200 is 2 times 100. And 100 is a perfect...

>> Susan: And next we are going to talk about some Nemeth reference sheets that Gloria Bennett, who is a colleague of mine, and I developed here way back in 2000 because some people...

Now we have seen how the cross product allows us to combine tuples and then apply selection conditions to get meaningful combinations of tuples. It turns out that relational algebra includes an...
