With

we can find

by substituting 4 into the main function.
So it would look like this:

Consider the given quadratic equation 

Comparing the given quadratic equation to the general equation
, we get a= 1, b=0 and c= -50
So, the solution to the quadratic equation is given by:





So, the solutions to the given quadratic equation are
.
<h3>-19 = -17 + k/5</h3>
<em>Multiply both sides of the equation by </em><em>5</em><em>.</em>
<h3>-95 = -85 + k</h3>
<em>Swap the sides so that all the terms of the variables are on the left side.</em>
<h3>-85 + k = -95</h3>
<em>Add </em><em>85</em><em> to both sides.</em>
<h3>k = -95 + 85</h3>
<em>Add </em><em>−95</em><em> and </em><em>85 </em><em>to get </em><em>−10.</em>
<h3>k = -10</h3>

These districts are best characterized as Proportional Representation districts.
What is Proportional Representation?
There are numerous types of proportional representation systems, but they all have two things in common. They start by using districts with multiple members.
Proportional Representation, abbreviated as PR, uses significantly bigger districts that elect multiple members at once, such as five or ten, rather than electing one member of the legislature in each local district. Second, the percentage of votes a party receives in these districts with several members determines which candidates gain the seats.
The Proportional Representation system of America overcomes the wide ranging drawbacks of single-district voting system like not representing the large number of voters, discrimination against third parties, etc.
