In this question, we are going to solve a quadratic inequality.
00:06
We have a population function, and we will use this population function to write an inequality to determine when the population is more than 460 ,000 organisms.
00:36
So i'm going to subtract 460 ,000 from both sides.
00:52
10 ,000 minus 460 ,000 is negative 450 ,000.
01:06
I can also simplify this equation a little bit more by dividing by 100.
01:16
Eliminate some of the zeros.
01:34
If i wanted to, i could even divide the entire inequality by negative 15.
01:45
600 divided by negative 15 is negative 40 and negative 45.
01:55
Divided by negative 15 is 300.
02:01
That will reverse the inequality.
02:05
So now i want to write this as an equation that can be solved...
