Finding Integer Roots of $h+k=2016$

In summary, the purpose of finding integer roots of h+k=2016 is to solve for the values of h and k that satisfy the equation and make it equal to 2016. This can be done through algebraic manipulation and substitution, and there are also other methods such as graphical and numerical methods. There are restrictions on the values of h and k for integer roots, and considering integer roots is important in many real-world applications and can lead to further insights in mathematics and science.

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

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...:eek:

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
 

FAQ: Finding Integer Roots of $h+k=2016$

Question 1: What is the purpose of finding integer roots of h+k=2016?

The purpose of finding integer roots of h+k=2016 is to solve for the values of h and k that satisfy the equation and make it equal to 2016. This can be useful in various mathematical and scientific applications, such as in analyzing data or solving equations in physics and engineering.

Question 2: How do you find the integer roots of h+k=2016?

To find the integer roots of h+k=2016, we can use algebraic manipulation and substitution. First, we can subtract k from both sides to get h=2016-k. Then, we can substitute different integer values for k and solve for h. The pairs of integers (h,k) that satisfy the equation will be the integer roots.

Question 3: Are there any restrictions on the values of h and k for integer roots of h+k=2016?

Yes, there are restrictions on the values of h and k for integer roots of h+k=2016. Since h and k are added together to equal 2016, their sum must be an integer. This means that both h and k must be integers or half-integers (i.e. a multiple of 0.5). Additionally, h and k can only take on values between -2016 and 2016, inclusive.

Question 4: Can we use any other methods to find the integer roots of h+k=2016?

Yes, there are other methods that can be used to find the integer roots of h+k=2016. For example, we can use graphical methods such as plotting the equation on a graph and finding the points where it intersects with integer values. We can also use numerical methods like iteration or approximation to find the integer roots.

Question 5: Why is it important to consider integer roots in solving equations like h+k=2016?

It is important to consider integer roots in solving equations like h+k=2016 because in many real-world applications, the values of variables are restricted to integers. For example, in counting problems or when dealing with discrete quantities, only integer solutions make sense. Additionally, finding integer roots can also help us understand the behavior and patterns of equations and their solutions, leading to further insights and discoveries in mathematics and science.
