You are awesome. I couldn't understand this at all during Precal today - thanks so much!

Okay, in a test do we need to give all those answers or is a couple enough?

When I graphed this polynomial on Desmos, I got (-1.202, 0) as the sole "zero" or solution. First question, if the polynomial degree is "3" why aren't there 3 zeros? 2nd, where is -1.202, 0 in your list of possible of zeros?

Great video! Trying to learn this stuff in only 8th grade isn't too easy
