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.

Definition

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.

House Minority Leader Nancy Pelosi (D-CA) is calling for a high level security briefing on the operations of Darrell Issa (R-CA), the chairman of the House Oversight and Government Reform Committee, in which he would have to be forthcoming about what information he has released and to whom after he got his hands on sensitive documents surrounding HealthCare.Gov. It would then be up to the Department of Justice to make a determination.

Driving While Black

“Stop and frisk” isn’t just a reality in New York City. New data shows how police target African Americans on highways across America.

 In investigatory stops, a black man age twenty-five or younger has a 28 percent chance of being stopped for an investigatory reason over the course of a year; a similar young white man has a 12.5 percent chance, and a similar young white woman has only a 7 percent chance. And this is after taking into account other possible influences on being stopped, like how you drive. Police focus investigatory stops on younger people, and so as people grow older they are less likely to be stopped in this way. But a black man must reach fifty—well into the graying years—before his risk of an investigatory stop drops below that of a white man under age twenty-five.

Stamp Out Classroom Bullying Meeting Basic Needs Reality Therapy: Power; Love and Belonging; freedom and Fun; Safety

CLASSROOM STRUCTURE: REALITY THERAPY  As educators become increasingly aware of the prevalence and harm of bullying, there have been major conferences, school-wide programs, and legislation in 47 states intended to curtail it. But a recent study suggests how simple exercises in the classroom, involving just small groups of students at a time, may also have a positive impact.ImageAnchor Charts      Cooperative Learning Resources

 When a Government seizes drug money, where does it go? Where does it end up. The Gov might as well sell the drugs directly–helping to ease the violence associated with dope sells. What’s the difference between the Gov seizing drug money and apportioning drug related property (BACK TO TAXPAYERS) and drug dealers making a living on the drug monies industry?
