Question 1108759: I have a test next week and need help knowing how to solve and work this problem out.
The Function D(x)=2375x^2 + 5134x +5020 models the totals number of AIDS deaths x years after 1984. What year were there 90,000 deaths?

The problem requires you to write this quadratic equation

2375x^2 + 5134x +5020 = 90000

and solve it.

The solution "x" which you will get, will be that "number of years" under the question.


Did the problem become more clear to you after my explanation ?
