mind whatever Start by factoring the numerator and denominator in
- 00:28
this case factor both by grouping well in the numerator
- 00:31
The first two terms have the common factor three y
- 00:34
and the second two terms have a common factor negative
- 00:36
for well in the denominator The first two terms have
- 00:39
the common factor to x and second new terms have
- 00:42
a common factor Negative one So that was conveniently factor
- 00:45
x squared minus three from both terms in the numerator
- 00:48
and three y minus four from both terms And the
- 00:52
denominator there yes so that's what it looks like And
- 00:54
then finally we just cancel the common factor three y
- 00:57
minus four and that's what it ends up with the
- 01:00
x word by three over two x minus one And
- 01:02
let's really it This expression can't be factored any further
- 01:05
Noah Seriously that's for the factoring It's factored or done
