What are the two complex roots of x^2 + 2x + 2 it claims that the answer is -1+i and -1-i, however, after running this through the quadratic formula i got this: -1 + sqrt(2)i -1 - sqrt(2)i can someone me, the lesson i am on has been very poorly put together and i really want to understand this.

-1+i and -1-i are the actual answers

if we want to find the roots of the equation , we can use the quadratic formula. for quadratic equation of the form , , corresponds to a = 1, b = 2, c = 2; the solution to the equation is given by

since ,

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
