The Babylonians

It all started around 3000 BC with the Babylonians. They were one of the world’s first civilisations, and came up with some great ideas like agriculture, irrigation and writing. They plotted the paths of the Sun, the Moon and the planets, and recorded them on clay tablets (which you can still see in the British Museum). To the Babylonians we owe the modern ideas of angle, including the way that the circle is divided up into 360 degrees (owing to a small miscalculation, one per day). We also owe the Babylonians for the rather less pleasant invention of the (dreaded) taxman. And this was one of the reasons that the Babylonians needed to solve quadratic equations.

if $x$ is the length of the side of the field, $m$ is the amount of crop you can grow on a square field of sidelength 1, and $c$ is the amount of crop that you can grow, then

\[ c = m x^2. \]

 Quadratic equations and areas are linked together like brothers and sisters in the same family. However, at the moment we don’t have to solve anything – until the tax man arrives, that is! Cheerily he says to the farmer “I want you to give me $c$ crops to pay for the taxes on your farm.” The farmer now has a dilemma: how big a field does he need to grow that amount of crop? We can answer this question easily, in fact

\[ x = \sqrt { \frac{c}{m} }. \]

Recognizing Factoring Patterns

Quadratic equations describe the motion of a baseball after it connects with a bat, and the acceleration of gravity at the Earth’s orbit.

The numbers -15, -5, -3, -1, 1, 3, 5, and 15 are all factors of 15 because they divide 15 without a remainder.
Factoring is an important process in algebra which is used to simplify expressions, simplify fractions, and solve equations.

A composite expression is similar in that it can be written as the product of two or more expressions. For example: x2 + 3x + 2 is composite because it can be written as (x + 1)(x + 2). (Recall that the FOIL Method shows that (x + 1)(x + 2) is equivalent to x2 + 3x + 2.) Here, (x + 1) and (x + 2) are factors of x2 + 3x + 2.

In general, a number is a factor of another number if the first number can divide the second without a remainder. Similarly, an expression is a factor of another expression if the first can divide the second without a remainder.


A prime number is a number greater than 1 which has only two positive factors: 1 and itself. For example, 11 is a prime number because its only positive factors are 1 and 11.

Factoring is a process by which a the factors of a composite number or a composite expression are determined, and the number or expression is written as a product of these factors. For example, the number 15 can be factored into: 1 * 15, 3 * 5, -1 * -15, or -3 * -5. The numbers -15, -5, -3, -1, 1, 3, 5, and 15 are all factors of 15 because they divide 15 without a remainder.

Introduction To Factoring

A composite number is a number that can be written as the product of two positive integers other than 1 and the number itself. For example: 14 is a composite number because it can be written as 7 times 2. In this case, 7 and 2 are called factors of 14.

Putin,Comey and Third-Party Candidates 2016 US Election

The number of votes Stein got in Michigan and Wisconsin exceeded the gap between Clinton and Trump in those states.  “We are scholars of politics and the presidency, but you don’t need to be an expert to know that a shift or addition of just a few thousand votes in one or two key states can determine the outcome of a presidential election. In other words, a handful of voters in the right place at the right time can truly change the course of American history. “

He has called global warming a hoax, denied the reality of California’s devastating drought, promised he would kill all domestic climate-related regulations (like the EPA’s Clean Power Plan), and vowed “We’re going to cancel the Paris climate agreement” — humanity’s last best chance to avoid catastrophic climate change lasting centuries.

Watermelon seeds help in improving male fertility.

Watermelon seeds,

are good sources of magnesium vital for normal heart functioning, maintenance of normal blood pressure, supporting metabolic process and protein synthesis. It is also beneficial in the treatment of cardiovascular diseases and hypertension besides controlling blood pressure and diabetes.Roasted watermelon seeds are served as a snack or used to garnish salads. In Nigeria they are used in certain soups. Watermelon seed oil is extracted from these seeds which is beneficial for your hair and skin. To say the least, watermelon seeds are edible and can be a healthy option.

watermelon seeds

are a rich source of nutrients and minerals and therefore, should not be discarded. These seeds have a hard outer covering so they should be chewed before swallowing to get their nutritional content. Some of the health benefits of watermelon seeds are given below. http

Watermelon seed tea is considered to be a natural diuretic helpful for kidney cleansing.


Food historians believe that African slaves helped introduce the watermelon, now the most consumed melon in the US. The fruit eventually became a major symbol in the iconography of racism in the United States through the “watermelon stereotype”. In various images, the fruit was used to paint African Americans as a simple-minded people who were happy when provided watermelon and a little rest.

Watermelon seeds can be baked with salt for a protein-rich and tasty snack, which has a similar flavor and consistency to pumpkin seeds, or prepared in a tea to maximize its diuretic effects.

How To Make Watermelon Seed Tea


  • 30-40 watermelon seeds, fresh or dried
  • water


  1. Crush 4 tablespoons of fresh watermelon seeds using a mortar and pestle, or grind them up in a food processor.
  2. Cook for 10 minutes in two litres of water over high heat.
  3. Drink the entire two litres of tea over a period of two days for full effect.

This tea is especially good for those with digestive issues, or those who are prone to urinary tract infections. So instead of opting for seedless watermelons – which are less flavourful than watermelons with seeds and are part of a relatively new strain of watermelon mass-produced for consumers – or spitting out the seeds and throwing them away, the next time you eat watermelon, consider saving the seeds to roast or brew in a tea. Your body will ultimately thank you for providing it with such a nutritious snack or beverage.Watermelon-eathealthylivefit_com
