Question 57889
For what values of x is the following expression undefined: 

(3x-2)(5x-4)
____________
(9x-6)(7x-1)
:
 This is undefined anywhere where the denominator is = to 0.
(9x-6)(7x-1)=0 makes the function undefined:
9x-6=0  and 7x-1=0
9x-6+6=0+6  and 7x-1+1=0+1
9x=6  and 7x=1
9x/9=6/9 and 7x/7=1/7
x=2/3 and x=1/7  makes the function undefined.
Happy Calculating!!!
