## Answers ( No )

x^2 + 8x + (4)^2 – (4)^2 + 22 = 0

(x + 4)^2 – 16 + 22 = 0, so that (x+4)^2 + 4 = 0.

Then sqrt( (x+4)^2 = sqrt(-4)

I JUST TOOK THE FLVS TEST

its c

x=-4 plus or minus i sqrt 6

I would immediately reduce this by div. every term by -2:

x^2 + 8x + 22 = 0

Next, I’d “complete the square:”

x^2 + 8x + (4)^2 – (4)^2 + 22 = 0

(x + 4)^2 – 16 + 22 = 0, so that (x+4)^2 + 4 = 0.

Then sqrt( (x+4)^2 = sqrt(-4)

x+4 = plus or minus i*2

x = -4 plus or minus i*2 (answer)
