Answer:
C & D
Step-by-step explanation:
x² + 3x - 3 = 0
a = co efficient of x² = 1
b= co efficient of x = 3
c = constant = -3
roots = (-b ± [tex]\sqrt{b-4ac}[/tex])/2a
= (-3±[tex]\sqrt{3^{2}-4*1*[-3]}[/tex] )/2*1
= (-3±[tex]\sqrt{9+12}[/tex])/2
= (-3±√21)/2
[tex]x = \frac{-3+\sqrt{21}}{2} ; x =\frac{-3-\sqrt{21}}{2}[/tex]
