How do you do this equation in set builder notation. Confusing me.

5(x-2)(x-1)
_________
30 (2-x)

Any help would be greatly appreciated!

Hello, afreemanny!

What is it that we are supposed to "do"?
. . It is <u>not</u> an equation.

The <u>domain</u> is: . {x | x ≠ 2, x ε R}

Question soroban:
I see why you state x <> 2 : makes denominator 0, of course;
BUT:
we have (x-2) in numerator, making numerator = 0:
so why can't x = 2 ? is 0/0 = 0 ?

0/0 is undefined, not 0.

Thanks

I am sorry I called it an equation! I am totally Algebra dumb!
The question asked to make the domain into the set builder notation.
My book ...for lack of a better word...."sucks". It does not explain much well. I went to the library last night to try to find a different book to help me.
