a rational expression Ask it nicely and you'll receive a

00:21

calm logical answer because it's rational on get it Never

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

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
