Answer:
D
Step-by-step explanation:
x=(-4(plus minus)sqrt(4^2-4*2*(-1))/2*2
x=(-4(plus minus)sqrt(16+8))/4
x=(-4(plus minus)sqrt(24))/4
x=(-4(plus minus)sqrt(2*2*6))/4
x=(-4(plus minus)2*sqrt(6))/4
x=(2(-2(plus minus)*sqrt(6)))/2*2
x=(-2(plus minus)*sqrt(6))/2
x=(-2+sqrt(6))/2
x=(-2-sqrt(6))/2
(Option 4 I think, but can see for sure)
