Answer:
[tex](y-3)(y-14)[/tex]
Step-by-step explanation:
The trick is to find two numbers that add to -14 and multiply to 33.
Quick glance at the sign first: product is positive, sum is negative, so you're looking at two negative numbers.
Now focus on 33. You can write it as either -33 times -1, or -11 times -3. If you try to add them up, you will get -34, or -14. We found our pair! At this point the trinomial is factored simply as
[tex](y-3)(y-14)[/tex]
