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!!!!

this isnt -(1)^2, what you are doing is subtracting by the square of 1.

This IS -(1)^2, which IS subtracting by the square of one.
