Step-by-step explanation:
Method for rounding:
Look at the number 1 place before the place you are rounding to.
If it is greater than 4: round up
otherwise: round down.
Ok,
here the number we're looking at is 8 cuz' 8 is in the ones place.
8 is bigger than 4 so we round up.

Answer:
The second one
Step-by-step explanation:
Answer:
x^2 + x + 2 = 0.
Step-by-step explanation:
The discriminant b^2 - 4ac is < 0 for complex roots.
So we can choose appropriate values for a, b and c.
Let b = 1, a = 1 and c = 2 so b^2 - 4ac = 1 - 4*1*2 = -7.
So our equation is:
x^2 + x + 2 = 0.
