MHB How to Understand the Ratio of Quadratic Roots?

Click For Summary
Understanding the ratio of quadratic roots involves solving for coefficients, particularly when dealing with monic quadratics. Participants emphasize the importance of these skills for Olympiad preparation, suggesting that brute force methods can be a fallback if time permits. The discussion highlights the necessity of showing work to clarify misunderstandings about the ratios and solutions. Overall, the conversation stresses both strategic approaches and the need for clarity in problem-solving. Mastery of these concepts is crucial for success in competitive mathematics.

Those are nice problems. If you're prepping for the Olympiad, you will need the skills. If all else fails, brute force it! Of course, if you're not fast enough, you'll waste too much time.

Personally, I wrote down the ratios and solved for b. You could solve for any of the 4 remaining arbitrary coefficients.

They were nice to you and made them both monic quadratics.

I didnt get it

Didn't get what? Ratios? Solve for...? Please provide YOUR work.
 
I have been insisting to my statistics students that for probabilities, the rule is the number of significant figures is the number of digits past the leading zeros or leading nines. For example to give 4 significant figures for a probability: 0.000001234 and 0.99999991234 are the correct number of decimal places. That way the complementary probability can also be given to the same significant figures ( 0.999998766 and 0.00000008766 respectively). More generally if you have a value that...
