[tex] {x}^{2} - 4x - 6 = 0 \\ x = \frac{4 + \sqrt{16 + 24} }{2} \\ x = \frac{4 + \sqrt{40} }{2} \\ x = \frac{4 + 2 \sqrt{10} }{2} \\ x = 2 + \sqrt{10} [/tex]
OR
[tex] {x}^{2} - 4x - 6 = 0 \\ x = \frac{4 - \sqrt{16 + 24} }{2} \\ x = \frac{4 - \sqrt{40} }{2} \\ x = \frac{4 - 2 \sqrt{10} }{2} \\ x = 2 - \sqrt{10} [/tex]
