Try studying alone or with another person, whichever works better for you. Make sure to get enough sleep and eat something before...

This is a video tutorial in the Education category where you are going to learn how to factor a trinomial by GCF then grouping method. For example how to factor the trinomial 6r(squared) â€" 28r + 16. The first thing is to get the greatest common factor (GCF) of the numbers. So, GCF of 6, 28 and 16 is 2. The trinomial can now be written as 2{3r(squared) â€" 14r + 8}. To factor by grouping, see the trinomial as the general formula of ar(squared) + br + c. To factor this, you got to look at the...

In this video, we learn how to make iodine easily. You will need potassium iodine and sulfuric acid to make this. First, add the acid into the potassium iodine slowly. After you add in each part, swirl the beaker slowly so it gets mixed together. After you have added in all of the potassium, you will place this into a beaker filled with ice water while you add in more, because the mixture gets really hot. When finished, you will end up with a mixture that is iodine and nothing else. Fill with...

Want to test whether the soil sample or a water sample contains boron, watch this video. As shown in the video, the first step is to create test specimens of various concentrations using a simple turmeric and ethanol solution as a base for comparison. The basis of this experiment is the fact that curumin present in turmeric reacts with boron to form a reddish compound and so the result of this reaction can easily be verified visually. The solutions of varying boron concentrations are...

In this tutorial, we learn how to avoid research paper plagiarism with quotations. Whenever you use a source, you can quote from it using the author's direct words, or you can paraphrase. Paraphrasing means putting something into your own phrases and sentences, because you will have to repeat certain key words. If you do this, you have to make sure you are not copying the quote exactly, and that it really is in your own words. You can't put something into your own words if you don't understand...

Factorization of a trinomial can be achieved by using the standard method of appropriately "splitting the middle term" or by this method as shown in the video. This method is essentially similar to the standard one. It involves splitting the first term (containing even powers of the variable) and then using the terms so obtained to form imaginary factors. The third term of the trinomial is then split and the values so obtained are substituted in the imaginary factors term by term until...

In this video, we learn how to write a good argumentative essay introduction. This is a persuasive essay that is just an argument. What makes this an essay is that it has an introductory section, main body, and concluding section. Many high schools and universities will require you to write an argumentative essay. You will first need to understand the process of writing the paper and then look at good and bad examples so you can get ideas of how the paper should look. Remember that you should...

In this tutorial, we learn how to add a footnote to a research paper. To do this, you will need to have all the sources written down where you got the information for the topics that you're writing about. Make sure you give credit to all the places that you go the information, or else you stole it and it's plagiarized. You will need to write down the author's name, title of the source, publication company, city of publication, copy date, and page number. To add the footnote, you will simply...

Perhaps not as easy as using a calculator, but easy nevertheless! With mathematics, as with anything else, not everyone progresses at the same rate. Happily, in the age of Internet video tutorials, this isn't a problem. Those who progress quickly can go beyond what's being taught them and those who are struggling likewise have all the time in the world to catch up. With this free video math lesson, you'll learn how to find square roots by hand.

If you're looking for an easy way to determine if a number is divisible by 3, then look no further than the divisibility rule. It's a shorthand way to tell if any given number can be divided by 3, without actually performing the division. Take the number in question, and if the sum off all the digits is divisible by 3, then the original number will be, too. There are four examples in this math video.
