Question

What are the possible values of x in x2 + 3x + 3 = 0?

Answer 1

Hello,

$x^2+3x+3=0\\ \Delta=9-4*3=-3\\ x= \dfrac{-3-i*\sqrt{3}}{2} \ or\ x= \dfrac{-3+i*\sqrt{3}}{2}$

Answer 2

$x^2 + 3x + 3 = 0$ 

$Apply \ the \ Quadratic \ Formula$ 

$Given \ the \ general \ form \ ax^2+bx+c=0$$there \ exists \ two \ solutions \ where: a=1, b=3 \ and \ c=3$ 

$x= \dfrac{-3+ \sqrt{3i}}{2}, \dfrac{-3- \sqrt{3i} }{2}$
