Today, we are doing more equations and their applications.
00:05
Here, we are going to be solving this quadratic polynomial equation.
00:10
In order to solve it, the first thing we want to do, simplify this denominator.
00:15
Instead of m squared minus 3m, it can be written as m m minus 3.
00:21
What that does for us is it gives us a common denominator of m times m minus 3.
00:26
So we can then multiply every term in the equation by that common denominator to get rid of all of our denominators.
00:38
These will then cancel.
00:40
Don't forget to distribute it there.
00:41
So we get 18 plus 2m.
00:54
1 second.
00:55
2m times m minus 3 equals this.
01:04
We'll cancel with this, which we'll give us 6m over here.
01:06
On this side, we want to distribute the 2m to simplify further, giving us 2m squared minus 6m equals 6m...
