Alright, so let's simplify this expression.
00:05
Now, if you look at the denominator, there's no coefficient in front of the t, so there's not a number i can pull out, and the one doesn't have a t, so there's no t i can factor out.
00:17
So it looks like the denominator is going to stay the same.
00:22
Hopefully, when we factor out the numerator, we get a t plus one that we can pull out.
00:27
Okay, so t squared.
00:30
So we can split the t's.
00:34
All right, and this one's pretty easy.
00:36
You have to find factors of one, which are just one and one.
00:40
They don't have any other factors.
00:42
And we need it to be zero in the middle because there is no t, right? and so it needs to be zero...
