ok so i'm kinda sort of confused...

I had this for a equation

X^2 + 4X - 1 = 0

and then I was like zero???
zero... really zero...
hmm...

X^2 + 4X - 1 = dy

????????
That zero does represent when Y equals zero correct??? this allows us to solve for X

OH!!!!!!!!!!!!!!

wait so I'm confused...

help me....

I'm not solving for X really am I... I actually solving for the derrivative of y??? when y approaches infinitely small or other words zero???

I'm confused can you clear this up for me
