The best way to improve your skill factoring this trinomials is just to practice and practice again.
So basically we need 2 numbers that multiply to 12 and that add up to -7. Using some intuition and some guess and check, we learn that the 2 numbers are -4 and -3. Putting them into 2 binomials, we get
(n-4)(n-3)
Hope this helps. If you found this helpful, please consider making this the brainliest answer because I just need one more best answer to be virtuoso. Thanks!
