Discussion Overview

The discussion revolves around the equation \( h+k=2016 \) and seeks to find integer values for \( h \), \( k \), and the roots \( \alpha \) and \( \beta \) of the quadratic equation \( x^2 + hx + k = 0 \). The focus is on the conditions under which these values can be determined, particularly emphasizing integer roots.

Discussion Character

  • Homework-related

Main Points Raised

  • Participants are tasked with finding integer values for \( h \), \( k \), \( \alpha \), and \( \beta \) given the equation \( h+k=2016 \).
  • There is a repetition of the initial question, indicating a possible request for clarification or emphasis on the problem.
  • One participant expresses gratitude, suggesting engagement with the content but not contributing further to the mathematical discussion.

Areas of Agreement / Disagreement

The discussion does not appear to reach any consensus, as there are no responses providing solutions or differing viewpoints on the problem posed.

Contextual Notes

The problem lacks specific constraints on the nature of \( h \) and \( k \) beyond their sum, leaving open questions about their individual values and the relationship to the roots \( \alpha \) and \( \beta \).

given $h+k=2016$, and the two roots $\alpha \,\, and \,\, \beta $ of equation $x^2+hx+k=0$ are all integers , please find the value of:
$h,k,\alpha \,\, and \,\, \beta$

$h,k,\alpha \,\, and \,\, \beta$

The roots are $\alpha,\beta$
$(x - \alpha) (x- \beta) = 0 $ or $x^2-(\alpha+ \beta) + \alpha\beta = 0$
comparing with given eqaution
$\alpha+ \beta= - h $ and $\alpha\beta= k$
from h + k = 2106 we get $\alpha\beta - (\alpha + \beta) = 2016 $
or $\alpha\beta - (\alpha + \beta) + 1 = 2017 $
or $(\alpha- 1)(\beta - 1) = 2017 $
as 2017 is a prime $\alpha = 2018$ and $\beta = 2$ and hence $h = - 2020,k = 4036$
or $\alpha = 2$ and $\beta = 2018$ and hence $h = - 2020,k = 4036$
 
$\alpha=2016,\,\beta=0,\,h=2016,\,k=0$ and any permutation thereof are also solutions.
Edit: sign error - the above is incorrect, sorry about that...:o

Thanks Greg

forgot the product to be (-1) and (-2017) which gives the above solution subject to the restriction that permutation of
$\alpha,\beta$ is possible but not any permutation
