Question 481738: Rational Expressions / Teachers question: For each equation, state the values of x that would result in division by zero when substituted into the original equation. show your work.
I will have to write it out as i cannot get the problem to look correct when I make it look like the book. so here goes
3 over X-9 = 1 over X squared - 9X plus 2
or
3
__
X-9
=
1
__
X sq - 9x +2
Thanks in advance =)

Here's the problem for reference:

One thing to always remember: You CANNOT divide by zero. So something like is undefined.

So this means that the denominators and CANNOT be equal to zero (to avoid division by zero)

So if , then . This means that if x=9, then the first denominator is zero, which is not allowed.

Also, if then which means that or when we solve for x. So if x=0 or x=9, then the second denominator will be zero, which is not allowed.

So the following values of x will result in division by zero: 0, 9
