Question 172554
Given the rational expression:
x^2-8x+12
__________ (divided by)
x^2-7x+6
state the restrictions on the variable x
:
Find the value of x that will give you 0 in the denominator
x^2 - 7x + 6 = 0
Factors to:
(x-6)(x-1) = 0
x = +6
and
x = +1
:
x cannot equal +1 or +6, any other value is OK

(if you substitute these values for x you have a 0 denominator, a big no-no in algebra)
