Hello, Morzilla!
Your work makes no sense . . .
Then at the end you add:
. . The problem I'm trying to work out is: .
If that's true, we have: .
Why are you messing around with conjugates?
I am not sure if I took down the correct notes but...
In rationalizing denominators, we multiply the denominator on both the top and bottom as such
X
=
in order to get rid of the negative we multiply by (-1) and get
again did I write my notes in the wrong way?!
The problem I'm trying to work out is
Thanks
Hello, Morzilla!

It would help if you copied the problem correctly.
And I don't like the way they left their answer . . . very childish!
Rationalize . . . multiply top and bottom by the conjugate . . .Rationalize: .
Multiply by
I don't know anyone past the age of puberty who leaves a negative denomiantor.
