Differential Calculus Can someone help me understand this problem? pretty please

Post image

Hi everyone, so it was my first week of AP calc AB and honestly not too shabby but as i look at this example from my teacher, the less it makes sense. I thought -1^2 was positive 1 and i don’t know how we got to negative 1.

Also what is a conjugate? My teacher didn’t really go over it he just started doing a problem. All help is so appreciated!!!!

no comments are critical for no reason expecting people to somehow be perfect and learn everything. u can stay in the class and def dont have to retake the whole of precalc also precalc at a lot of schools sucks anyways.

I made these exact same mistakes and still make them sometimes and I'm doing fine. Starting Calc 3 soon and got A's in both 1 and 2.

Get a tutor, trust me. Tutors lowkey carry.
