The Deep Dive

To find the values of that make the denominator zero, we’ll need to factor the quadratic equation . First things first, multiply the leading coefficient (2) by the constant term (-6) to get -12. Now, we need to find two numbers that multiply to -12 and add to 11. Surprise! Those numbers are 12 and -1.
Next, we can rewrite the expression:
This allows us to group terms:
Factor those groups:
Now, factor by grouping:
So the values where the function will not be a real number (because the denominator is zero) are when or , leading us to crucial solutions:
These values make your function undefined! Be sure to avoid them when you’re working with this rational function.
