Phase 1 http://en.wikipedia.org/wiki/Yang_Hui Yang Hui Yang Hui lived in the 12 century. He went to Lin-chi school. He wrote many books. Such as, Xiangjie Jiuzhang Suanfa. he worked on magic squares, magic circles, and binomial theorem. Yang hui's predecessor was Jia Xian. Jia Xian discovered pascal's triangle. It is the same as 'Yang Hui's triangle'. Also, Yang was a contempory to the other famous mathematician Qin Jiushao. Yang Hui died in the year 1298. Brahmagupta [[[]]] He was born in 598 CE and died in 668 CE. Brahmagupta was the leader of the astronomical observatory at Ujjain. In his tenure there he wrote four texts on mathematics and astronomy. He gave the solution of the general linear equation in chapter eighteen of Brahmasphutasiddhanta. Also, he gave to equivalent solutions for the general quadratic equation. Brahmagupta was trained by his father. he was skilled in many areas of mathematics. Such as, geometry,algebra,trigonometry, and many others. he was the most prominent indian mathematician of his time. he lived most of his time in bhinmal city in the state of Rajasthan of northwest India.

Phase 3 x^2+14x+33=0

Phase 3: Three Days: 30 points You will be given a quadratic Equation; you will come and get your equation from me when you reach this phase. A quadratic equation is an equation that can be written in the form ax^2+bx+c=0. GRAPHING DEFINITION





1. You need to explain what does it mean to say “ solve by graphing”once you have this written on your wiki you will solve the quadratic by graphing. (10 points) Using the zero property to solve equations of the form ax^2+bx+c=0 if the quadratic expression can be factored. FACTORING DEFINITION

2. You need to explain what it means to say “solve the quadratic by factoring.” Once you have this written on your wiki you will then solve the same equation by factoring. What do the solutions represent after factoring a quadratic (10 points) It solves for x. QUADRATIC FORMULA DEFINITION

 3. Last you need to explain what it means to say “solve the equation using the quadratic formula.” Put your explanation on your wiki and then take your equation and use the quadratic formula to solve it. Show the step-by-step process in solving this, on your wiki. (10 points)
