Best ResponseYou've already chosen the best response.1\(3x2 + 6x + 15 = 0\) \(x^2 + 2x + 5 = 0\) \(x = \dfrac{b \pm \sqrt {b^2  4ac}}{2a} \) \(x = \dfrac{2 \pm \sqrt {2^2  4(1)(5)}}{2(1)} \) \(x = \dfrac{2 \pm \sqrt {4  20}}{2} \) \(x = \dfrac{2 \pm \sqrt { 16}}{2} \) \(x = \dfrac{2 \pm 4i}{2} \) \(x = 1 \pm 2i \)
