For this one here, we're trying to get the least common denominator.
00:04
So i have 5 minus x and x minus 5.
00:07
Now, these ones here are the ones to always be aware of when they look very similar, but they're reversed.
00:13
On the fraction on the left, i can factor out a negative 1.
00:16
So i would have 2x over negative 1.
00:20
And when i do that, i now have an x minus 5.
00:24
So what we can see between the two of them is that they already both have an x minus 5.
00:29
So when i go to do the least common denominator, i'm going to have the negative one from the one on the left and then the x minus five.
00:38
Now, you can distribute this through if you'd like and have that common denominator of five minus x, but it's not necessary.
00:47
Common practice with this is to move that negative to the numerator.
00:51
So, for example, in the one in the left, i'm going to move that negative up with a 2x...
