Question

What kind of solution(s) does ax^2-bx+c=0 have if b^2-4ac<0?

a. two real solutions
b. one real solution
c. one complex solution
d. two complex solutions

Answer 1

liike the other user said

when the discriminant is less than 0, you get 2 complex roots

D is the answer

Answer 2

The discriminant is the value that is b^2 - 4ac.
When this number is <0 there will be 2 complex solutions. Letter D.

You would be taking the sqrt of a negative number resulting in a
" +- i sqrt of a number"
