You will definitely need brackets to properly show these expressions, I will assume you meant:
(3x-6)/(x-2)
= 3(x-2)/(x-2)
= 3, x ≠ 2
You take over to do (x-2)/(x^2 +3x-10)
hint: become very suspicious that perhaps one of the factors in the bottom might be (x-2)
Simplify the rational expressions. State any excluded values. Show your work.
8.3x-6/x-2
9.x-2/x^2 +3x-10
please.

on my exam it shows like fraction way of it with the "___" line in the middle that's why i put "/" so didn't know how to write it but yes that's what i meant :)
and no the (x-2) is on top and the /(x^2 +3x-10) is on the bottom
and no the (x-2) is on top and the /(x^2 +3x-10) is on the bottom
But I want you to factor the bottom, and my hint was that one of the factors is (x-2)
so (x^2 + 3x - 10) = (x-2)( ...... )
and the x-2 will cancel
so (x^2 + 3x - 10) = (x-2)( ...... )
and the x-2 will cancel
so how do i get the answer?
