Question

find the solution set in a+bi form: x^2 +6x +12 =0
you dont have to show the work because i have the answer i just wanna check it.., thanks -D

Answer 1

-3±i√3

As you requested, no work is shown.

Answer 2

{ -3 - i sqrt(3) , -3 + i sqrt(3) }

Answer 3

x^2 +6x +12 =0

Discriminant = (6)^2 -4(12)(1) = 36 - 48= -12 = 12i^2

x1 = (-6 + i sqrt(12))/2 = -3 + i sqrt(3)
x2 = (-6 - i sqrt(12))/2 = -3 - i sqrt(3)

Solution set =
{ -3 - i sqrt(3) , -3 + i sqrt(3) }
