Guess and check. Pick a few values and plug them in to the equation. Did any of your guesses work? If not, then narrow it down and make another guess or two. It's really just about learning the process of guessing and checking.

Use the guess and check method to factor a trinomial. Find the factors of the coefficients, then plug some in and check if they work. If it doesn't work then plug in some different factors or rearrange the factors and check again. You...

Greatest common factor, grouping terms, binomials, difference of squares, sum or difference of cubes, are some of the factoring strategies that can be used. Sometimes it takes more than one of these methods to solve a problem. Hear the...

More practice never hurt. A short video shows how to factor quadratics with a leading coefficient that is not one. The main idea presented in the video is a guess-and-check method. Pupils complete problems on their own to further hone...

Build a strong understanding of equations with a video that shows pupils how to solve through inverse operations. The narrator explains the concept of solving equations by using operations that balance each side. She solves both a...

Factor the given quadratic equation by using the guess and check method. Then use the zero product property to find the solutions to the quadratic equation. Don't forget to check both of the answers.

The instructor defines a prime polynomial as much the same as a prime number: they only have two factors, 1 and itself. She further demonstrates what a composite polynomial is to give an example of a polynomial that is not prime.

And the prize for oldest living thing on Earth goes to . . . In this video from PBS Digital Studios, viewers learn about the oldest living things on Earth, all over 2,000 years old, such as bristlecone pines, baobab, sea grass,...
