All variables have a coefficient. Integers, decimals, and fractions can represent coefficients, positive or negative. And there are times there is no written coefficient which means it's really just 1. This short video demonstrates and...

So you are looking for all the possible binomial factors of a trinomial expression? First find the factors of the coefficients. Then set up a table or template to do a guess and check. Write out, using the template, all the possible...

Got a fraction in your equation? Don't like that fraction? Just multiply both sides by the reciprocal of that fraction to get rid of it. Now you can solve the problem using the steps necessary to isolate your variable. Don't forget to...

What is a constant variation? How can something change and be constant? Oh, the rate of change is constant. So if there are two variables that are directly proportional they can have a constant of variation? Yes! Still a bit confused?...

If you or your class members are interested in how the quadratic formula is derived, then take a look at this video! The tutorial takes you through each step necessary to derive the quadratic formula from the general form for a quadratic...

The instructor does a very good job of explaining all the things you need to do to find the integer values of this given trinomial. She demonstrates how to set up a template to be able to check the signs of the terms. Next step, what are...

Coefficient is a basic term everyone needs to learn before studying Algebra. Learn the definition of a coefficient by watching this video that explains the meaning with examples.

Combining like terms together is a key part of simplifying mathematical expressions, so watch this tutorial to see how it is done. [7:25]

This video explains what the words term, factor, and coefficient mean.

This video tutorial features three lessons that explain how to change equations in slope-intercept form to standard form as well as how to write an equation in standard form using two points. A real-life word problem is also included...

Synthetic division is investigated in this video lesson. The tutorial provides a detailed example demonstrating how to find the real roots of a function.
