I know its not D because it does not have the +-sign

Vocaloid:

if you solve the quadratic equation you get two complex roots

zarkam21:

Vocaloid:

yes, in general complex roots come in pairs

eriley:

i think it is a

zarkam21:

Okay perfect thanks

Vocaloid:

OR you can graph them and see if the graph touches the x-axis

zarkam21:

Okay and see how many times it touches??

eriley:

no problem

Vocaloid:

in this case, the graph does not touch the x-axis at all so there cannot be any real roots

zarkam21:

Got it. So it is D

Vocaloid:

wait hold on I graphed the wrong function ugh

Vocaloid:

when you graph/solve this you actually get two distinct, real roots ;_;

zarkam21:

SO c/

Vocaloid:

yeah sorry about that ;;
