Homework Help: Algebra II

Posted by Jonathan on Wednesday, August 8, 2007 at 4:34pm.

Write y=x^2+4x-1 in vertex form.
y=x^2+4x-1
y=(x^2+4x+8)-1-8
y=(x+2)^2-9

This isnt one of my answer choices,what am I doing wrong?

in second line:

y=(x^2+4x +4 )-1 +4

(take one half of the middle coefficient, then square it)

y=(x^2+4x + 4 )-1 - 4
