$\frac{ {x}^{2} + 3}{ {x}^{2} - 11x - 12}$

Because which numbers will make the expessions undefined. We will focus on the denominator only.

Factor the terms.

$(x - 12)(x + 1)$

Now which 2 numbers that will make these terms become 0?

12 and - 1 of course.

So these 2 numbers that will make the expressions undefined are 12 and - 1
