Using the quadratic formula,
∆=b²-4ac
∆=(3√3)²-4(1)(6)
∆=(9×3)-4(6)
∆=27-24
∆=3
[tex]x1 = \frac{ - b - \sqrt{3} }{2a} = \frac{ - 3 \sqrt{3} - \sqrt{3} }{2} = \frac{ - 4 \sqrt[]{3} }{2} [/tex]
[tex]x1 = - 2 \sqrt{3} [/tex]
Similarly,
[tex]x 2 = \frac{ - b + \sqrt{3} }{2a} = \frac{ - 3 \sqrt{3} + \sqrt[]{3} }{2} = \frac{ - 2 \sqrt{3} }{2} [/tex]
[tex]x2 = - \sqrt{3} [/tex]
Method 2:
x²-Sx+P=0
where S is the sum of the roots & P is the product of the roots.
x¹+x²= -3√3
x¹x²=6
Solving the system you get the same answers.
Your factored equation can be written in the form of:
(x-x¹)(x-x²)
(x+2√3)(x+√3)
