I dont understand this problem
Fiesta28 [93]

Answer:

D and F

Step-by-step explanation:

x^{2}+4x+4=12 can be rewritten as x^{2} +4x-8=0.

From there you can use the quadratic formula x=\frac{-b±\sqrt{b^{2}+4ac } }{2a} (ignore the A, I can‘t seem to remove it), where a=1, b=4, and c=-8.

x=\frac{-4±\sqrt{4^{2}-4(1)(-8)} }{2(1)}

Then you get x=\frac{-4±\sqrt{16+32}}{2}

Then you get x=\frac{-4±\sqrt{48} }{2}

So x=-2±\frac{4\sqrt{3} }{2}

Which means x=-2+2\sqrt{3} or -2-2\sqrt{3} which are choices D and F.
