You can
put this solution on YOUR website!200000/x=c where x is the number of people in the club
:
200000/x+5=c-2000
:
so
---> multiply all terms by x(x+5)
:
distribute
:
200000x terms cancel each other and divide rest of terms by 2000.
:
--->x^2+5x-500=0}}}
20 and -25 are the values for x but we know there arent negative people so 20 is our value for x meaning that
:

| Solved by pluggable solver: SOLVE quadratic equation with variable |
Quadratic equation  (in our case  ) has the following solutons:
For these solutions to exist, the discriminant  should not be a negative number.
First, we need to compute the discriminant :  .
Discriminant d=2025 is greater than zero. That means that there are two solutions:  .
Quadratic expression  can be factored:
Again, the answer is: 20, -25.
