What is the x of 2/3x squared minus 6x plus 15

(2/3) x^2 - 6x + 15 = 0

Using the quadratic formula:

x = [-b + - sq root (b^2 - 4 * a*c) ] / 2a

x = [--6 + - sq root (36 - 4 * (2/3) * 15] / 2 * (2/3)

x = [6 + - sq root 36 - 40] / (4/3)

x1 = 4.5 + (2i / (4/3))

x1 = 4.5 + 1.5i

x2 = 4.5 - (2i / (4/3))

x2 = 4.5 - 1.5i
