Welcome all to SPM Board! This is a thread where you put your doubts and curiosities into discussion with others. This is not a public thread to ask for answers and solutions to your questions from homework, tests and past year papers.
This thread has advice on the following aspects of writing a good question on this site. Each item in this list links to an answer below about that specific aspect of question writing.
Include your work
You have a question, and if you post it here, you've probably attempted, and failed, to solve it yourself. It is much easier for others to judge the most appropriate level for an answer to your question if you provide these attempts. So you'll receive answers better suited to your specific needs.
Including your work also shows to the community that you're not using this website as an answer machine -- such as , your question will be received more positively.
A further benefit of writing down precisely what you've tried is that, in the process of doing so, you will very likely spot your error and solve your problem yourself. Bonus!
Provide some motivation to your question.
Instead of just asking us to find the roots of an equation, tell us where the equation comes from. This is especially the case when your equation comes from models of the physical worlds: those kinds of intuition are great guiding principles for formulating an answer.
