Question 178478This question is from textbook Discovering Advanced Algebra
: I need assistance with this problem.
Simplify the expression and identify values for which the expression is undefined......
+%28%282%2Fy%29-1%29%2F%28%283%2Fx%29%2B1%29+

I think that the undefined values for x are -3 and 0 and for y is 0 since those values would cause a denominator to become 0.
Please confirm my logic and help with simplifying. THANKS This question is from textbook Discovering Advanced Algebra

Simplify the expression and identify values for which the expression is undefined......
((2/y)-1)/((3/x)+1)

I think that the undefined values for x are -3 and 0 and for y is 0 since those values would cause a denominator to become 0.
----------
The undefined value for x is 0; the undefined value for y is 0.
-------------------
Simplifying:
= [(2-y)/y] / [(3+x)/x]
Invert the denominator and multiply to get:
[(2-y)/y] * [x/(3+x)]
= [x(2-y)]/[y(3+x)]
