More silly leprechaun math
The issue is that x > 3 so that the square root of (3-x)^2 is x-3 (not, as is shown, 3-x) since square roots are always nonnegative.

I would tell my students, “When you’re trying to solve a problem there’s only a few things that can affect the outcome, only a few things you need to check. If A doesn’t work and B doesn’t work, then C will almost certainly work.” When you’re trying to figure why you’ve come up with x=y when you know x is not equal to y, it’s either because you’ve divided by zero (not the issue here) or because you’ve messed up an absolute value.yeah, just what I was going to say

All x<0?Give an example of
|x| = -x
Meaning, find a nonzero value of x for which the above equation is true.
All x <= 0, precisely. Attaboy. Now, off to the gym!All x<0?
Would that make you LionGym?All x <= 0, precisely. Attaboy. Now, off to the gym!
Yes. When my time comes they’ll be carrying me out of there. I said this to a couple guys today and they both nodded.Would that make you LionGym?

This is what I'm up against.
