Question

What is 4x^2+4y^2+4x-15=0 in standard form?

A. (x+4)^2 + (y+4)^2 = 8
B. (x+1/2)^2 + y^2 = 4
C. x^2 + (y+1/2)^2 = 25
D. (x-4)^2 + (y-4)^2 = 64

Answer 1

looks like you want to complete the squares ... at least for the x parts since there is only 1 y part

Answer 2

err, standard form may mean something different than what i am thinking tho ... so context would be useful

Answer 3

@amistre64 does the answer choices help?
