Dear Maths Gang,
Your task is to produce a poster about how to solve quadratic equations (ax^2 + bx + c = 0).
It should include:
- How to factorise (perhaps including how to factorise equations that have more than 1 x^2 value).
- How to use the quadratic formula
- How to complete the square. (You might also include how to derive the quadratic formula by completing the square).
- Examples of how to do the above.
I’d particularly like it if your poster could include the strengths and weaknesses of different methods….
Good luck! You can leave a comment if you have any questions!
