Not sure where to begin on this one. If you tell me how to do this one, it'd help me with the others. :D

Oh yeah, I always forget to do that!

Now I'm having trouble with this! (Headbang)

(x-2)(x-2) doesn't work.

(x+2)(x-2) doesn't work...

Wait.

Is there no solution? - Jul 15th 2008, 08:08 PMIsomorphism
Sigh...

x^2+ 4x + 1 = - 3

x^2+ 4x + 4 = 0

(x+2)^2 = 0

x = -2

Substiute this value in y = x^2 + 1 = (-2)^2 + 1 = 4+1 = 5 - Jul 15th 2008, 08:10 PMmankvill

I know, I'm just taking a test right now! Gotta be sure.

Thanks!
