Answer:
C
Step-by-step explanation:
Solve the quadratic in answer choice C using the quadratic formula:
[tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex].
Here a=1, b=2, and c=17.
Substitute and you'll have:
[tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{-2+/-\sqrt{(-2)^2-4(1)(17)} }{2(1)}=\frac{-2+/-\sqrt{4-68}}{2)}[/tex]
[tex]\frac{-2+/-\sqrt{-64} }{2}=\frac{-2+/-8i }{2}=-1+/- 4i[/tex]
