comment The minimum value of $\frac{a(x+a)^2}{\sqrt{x^2-a^2}}$
Oops. It was for an applied optimization problem. It didn't explicitly say "maximum," but I didn't want to include the extra info, just the derivative. I will edit

@user164587 Haha, I hadn't ever noticed that. I'm in Calc 1 and we still use log as base 10 if not specified. And most, if not all calculators, naturally use base 10

comment Prove rigorously: $\displaystyle \lim_{x\rightarrow 2}x^2+5x=14$
So it's like squaring both sides? (But multiplying by equivalents)

How did you find $|x-2||x+7|<(9+ \delta)\delta $?

$\delta>|x-2|$?

There was an error in my question (wrong function). This is relevant. Sorry for the confusion
