you need to find k so that simplifying the equation to x^2+4x+1+k is a double root

so 2+3=-x+k
wtf
make that x^2+4x+1-k
I think I get it
yeah -x+k=x^2+3x+1
you need to find k so that the equation equals (x+C)^2
and then their derivatives should be = too
I got this
no derivatives are needed, its just completing the square
fuck that
you did completing the square in geometry, right?
k=-3
yes
dont remeber it at all but I have heard of it
idk but my way worked
(x+2)^2=x^2+4x+4
I took the derivatives of both equations and set them =
meaning there's only one point of intersection
meaning its tangent
and solved for x
that works too
then I set the equations = and pluged in x
so you factored out an x+2
completed the square
however you do that
your way seems more complicated
my way doesn't use calculus, which means i don't have to think as hard before bed
its also only viable because of the 4x term being nice

Ah fire doesn't have hl2: Episode 2. thats why he's missing shit
what a guy
knew it
yeah lot of things want that
NotLikeThis
actually that's a lie
you'll be fine
it's euros
fucking euro trash
it'll go on sale at some point for real cheep
it's fucking steam
that's how i got garry's mod and counterstrike source for like half a euro
also rip @Dan K. Meme Fuck that guy Kappa
