QUADRATIC EQUATIONS

ALGEBRA:

QUADRATIC EQUATIONS.

Are equations where the highest exponent of variable  x is a square e.g x²

The Standard Form of a Quadratic Equation looks like this:

 

• a, b and c are known values. a can't be 0.

• "x" is the variable or unknown (we don't know it yet).

Here are some examples:

2x2 + 5x + 3 = 0		In this one a=2, b=5 and c=3
x2 − 3x = 0		This one is a little more tricky: Is this equation a quadratic equation? what is the value of ; a=?      b=?           c=?
5x − 3 = 0		Is this equation a quadratic equation?  what is the value of ; a=?      b=?           c=? SOLVING QUADRATIC EQUATIONS BY FACTORIZATION.   Product = C Sum = b When C is Positive (+) then two number all positive (+) or all negative (-). When C is negative, one number is a +and the other a - EXAMPLES: 1.        x² − 12x + 36  product = 36 , (-6 x- 6) Sum =  - 12 , (-6 + -6)               can be factored as (x − 6)(x − 6). (Roots) 2 .            2x² +5x + 3  product = 6, (3 x 2) Sum =  5,  (3+ 2) can be factored as?

Unit 3: Criterion A: Inquiring and Analysing

Green Technology Unit Criterion A: Inquiring and Analysing Summative

Teacher(s)	Victor, Ben	Subject group and discipline	Design (DD)
Unit title	Green Technology	MYP year	MYP 4	Unit duration (hrs)

Inquiry: Establishing the purpose of the unit

Key concept	Related concept(s)	Global context
Change	innovation	Globalisation & sustainability
Statement of inquiry
The success of innovations is pegged on sustainable changes.
Inquiry questions
Factual— Is Renewable Energy Sustainable? Conceptual— To what extent have the changes in innovation impacted the environment? Effects of information technology on Environment Debatable— Will our environmental problems be addressed if we fully use renewable energy in all our systems? Focus area: Human activities that have impact on the environment.

Challenge

As human beings scramble for finite resources to satisfy their unlimited needs, they have impacted negatively on the environment through industrialization and population growth which has led to numerous environmental degradation through; Air Pollution, Water Pollution, Soil Pollution, Technological invention and poor waste management. All of these problems pose as the recipe for Global Warming which has remained a global phenomenon to the entire universe. These problems can be solved easily by introducing new or existing information technology solutions that will remain environmental friendly with positive impact to the ailing environment. The digital solutions can be used to transform, educate, advocate and create alerts by providing platforms to nurture, restore and protect our mother nature through green technology.

Your task is to identify an environmental related problem/challenge locally or internationally that can be addressed or solved using an IT based solution that support green technology in totality. The problem should be clearly described and the client's or target audience's current way of addressing the situation described. The problem description should include the current limitations the client is facing and detailed explanation of why you think an IT solution will be the best.

Criterion A: Inquiring and analysing

Maximum: 8

Students identify the need for a solution to a problem. At the end of year 4, students should be able to:

      i.  Explain and justify the need for a solution to a problem for a specified client/target

 audience : 1 page. discuss the environmental problems and how long it has persisted,  show how it has affected the client 

and community, show how the client is in dire need for solution, justify by giving examples on why such a problem needs a quick 

IT solution.

     ii.  Identify and prioritize primary and secondary research needed to develop a solution to the problem: 
2 pages. A table of research plan indicating questions relevant from primary and secondary sources. 
A summary of the feedback from research.

Task	Priority	Why is it        important	Sources	Completion date

   iii.    Analyse a range of existing products that inspire a solution to the problem:
4 pages: analyze 5 applications relevant to the IT tools you chose by using a table. 

Application	Advantages	Limitation

analyze 5 existing  products created to solve similar environmental problems . (paragraph)

    iv.     Develop a detailed design brief, which summarizes the analysis of relevant research. 
2 pages.

- write a detailed design brief that outlines, the client/target audience opinion, the experts opinion, and your personal opinion. discuss the IT tool you will use, discuss the key features of the tool, specifications  and its benefits to the client based on your research.

Capture; key concept- Change, related concept- Innovation and global context-Globalisation & sustainability

Sample Criterion A Document

1. In-Text Citation.

In - Text Citation allows the reader to know what ideas, opinion and facts are the author's and what came from the source. The citation also refers the reader/ examiner to the reference page at the end for full citation.

In APA style, in-text citation are composed of author's last name, date/year of publication and the page number. (Truner, 2003,p.34).If you include a page range, use two ps followed by a period (Wafula, 2015, pp.34-35). The sentence period comes at the end of closing parenthesis.
