To solve for k, just plug in the x provided:

12^2 - k(12) - 36 = 0

144 - k(12) = 36

-k(12) = 1/4

k = -1/48

Most times, it’s good to talk to your teacher for help. I think it would be a good idea to ask your parent, sibling or any adult for help. Sometimes you think harder than you should so relax and try reading the question again. I hope you figure this out! Good luck!
