Question

If the discriminant of a quadratic equation is 4, which statement describes the roots?
-2 complex roots
-2 real roots
-1 real root
-1 complex root
PLEASE HELP

Answer 1

well is the sqrt(4) real or imaginary ?

Answer 2

real ?

Answer 3

yep assuming all real coefficients of the quadratic
let D=discriminant
If D=0 we have 1 real
If D=positive we have 2 real
If D=negative we have 2 complex

Answer 4

so it would be 2 real ??

Answer 5

yep but that is with the assumption your quadratic is only made up of real coefficients

Answer 6

thanks
