You follow the rules for the quadratic formula, where

x= (-b +- √(b²-4ac) )/2a

Filling a, b and c in yields

x = (8 +- √(64-164) ) / 2 =>

x = (8 - √-100)/2 or x = (4 + √-100)/2

Well, √-100 = 10i, so then you simplify to the last answer, D:

x = 4-5i or x=4+5i

Answer:

x = -11

Step-by-step explanation:
