Use completing the square to rewrite the following equation in transformational form: y = x2 - 12x + 7 A. y = (x+6)2 + 43 B. y = (x-6)2 + 43 C. y = (x+6)2 - 29 D. y = (x-6)2 - 29

i'd say the answer is C

OpenStudy (anonymous):

C or A

OpenStudy (cwrw238):

x^2 - bx + c = (x -(b/2) ^2 + c - (b/2)^2

OpenStudy (cwrw238):

plug n b = 12, and c + 7 into the above identityy and you'll get it

OpenStudy (cwrw238):

* plug in

OpenStudy (anonymous):

@cwrw238

OpenStudy (anonymous):
