Teaching The Quadratic Formula

By | April 27, 2018

This equation is known as the quadratic formula. The first known solution of a quadratic equation is the one given in the Berlin papyrus from the Middle Kingdom (ca. 2160-1700 BC) in Egypt.

Like most elementary mathematics, solving quadratics is more important as example illustrating broader lessons than as a fact in itself. Here are two broader lessons that stand out to me: 1) Quadratic equations are often the first problems you en.

Now we can solve a Quadratic Equation in 5 steps: Step 1 Divide all terms by a ( the coefficient of x2). Step 2 Move the number term (c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation. We now have.

The Greeks were able to solve the quadratic equation by geometric methods, and Euclid's (ca. 325-270 BC) Data contains three problems involving quadratics. In his work Arithmetica, the Greek mathematician Diophantus (ca. 210-290) solved the quadratic equation, but giving only one root, even when both roots were.
