When you run into indeterminate forms, you can factor to cancel out terms and solve for the limit!
Indeterminate form essentially means an unknown value that's not solvable mathematically.
Scenario: Evaluate the limit of the below function at x = 3.
PRO TIP: The most common indeterminate form that you'll work with is "0/0".
We can factor the numerator here (since it's a polynomial)...
x2 - 1x - 6
...and to do so, ask yourself: what two numbers add to -1 and multiply to -6?
-3 + 2 = -1
-3 x 2 = -6
This means we can factor like so!
