Quadratic Equation: Find Roots Range

Click For Summary

Homework Help Overview

The discussion revolves around a quadratic equation of the form ax^2 + bx + c = 0, specifically focusing on the conditions under which the roots y and z exist based on the inequality a(12a + 5b + 2c) > 0. Participants are exploring the implications of this inequality on the range of the roots.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are examining the relationship between the coefficients of the quadratic equation and the roots, questioning how the given inequality affects the roots' range. Some are attempting to derive conditions from the sum and product of the roots.

Discussion Status

The discussion is ongoing, with participants providing insights and questioning assumptions. There is a call for the original poster to show their work, indicating a focus on collaborative exploration rather than direct answers. Some participants are suggesting potential approaches based on quadratic properties.

Contextual Notes

There is an emphasis on the requirement for participants to demonstrate their own work, reflecting the forum's policy against providing direct solutions. The original poster's inquiry is framed within the context of homework help, which may impose certain constraints on the discussion.

If a(12a+5b+2c)>0 and the equation ax^2+bx+c=0 has roots y and z , then find out the range of the roots of the equation ...

For brainy students!
 
Is this a homework question of yours?
 
Insulting our intelligence isn't very nice if you're asking for help!
 
Well, so you have got:
ay^{2}+by+c=0
az^{2}+bz+c=0
Along with your inequality.

Have you any brainy suggestions of your own?

antiparticle, as I told you in my warning just now as I moved this to the Homework Help forums, you MUST show your own work on this homework/coursework question. We do not do your work for you, and we do not help you cheat.

Show us your work.
 
From the sum and the product rule of the quadratic equation we can easily get
12-5(y+z)+2yz>0..
and from this one we can get some conditions..
