Math is fun! That is a statement that not many people find to be true. But it can be if you understand it and know a few tricks to solving certain problems. In this tutorial, you'll find out how to connect interval notations and compound inequalities. Don't know what those wor ...more

Learn how to use the FOIL method to distribute two binomial expressions in algebra. The FOIL method — which stands for first, outer, inner, and last — takes two binomials and multiplies them for a single quadratic equation. Solving for binomials with FOIL takes just a few step ...more

Solving the Inequalities using graph, first you have to take the inequality equation into equal. Then convert the equation into straight line equation i-e(y=mx+c). Giving own values for 'x' like (-1, 0, 1) we would get the value for 'y'. By plotting these points in the graph, ...more

This video deals with solving quadratic functions. It does not involve the use of the quadratic equation; rather, only factored equations are used. The speaker starts out with a factored quadratic equation. The speaker goes on to do the mathematical steps necessary to find bot ...more

A Teacher shows us how to graph compound sentences with the word "or" in them. These graphs will have arrows pointing out in different directions. On the number line draw arrows from the numbers in your compound sentence. So for example if after solving a problem with inequali ...more

This is an instructional video on how to "complete the square", which is an algebraic technique for solving a quadratic equation. The instructor starts by showing you what a quadratic equation actually is. He describes what "completing the square" actually means, and how it ca ...more

In this video the instructor shows how to shade a system of inequalities. He says that shading a system of inequalities is similar to shading a single inequality but in the former case you tend to shade more than one inequality in the same graph. He shows how to do that using ...more

On Yay Math, Robert Ahdoot, founder of Yay Math, will show you some square root functions and some inequalities. He begins with the problem y=x². Then he makes a sketch with two intersecting lines in a t shape. The problem is illustrated by a curved U shape, the U's bottom res ...more
