18x^3 - 24x^2 + 30x= 6x(3x^2 - 4x + 5)

6*x*(3*x^2 - 4*x + 5) = 0
6*x = 0, x1 = 0
3*x^2 - 4*x + 5 = 0
a = 3, b = - 4, c = 5
b^2 - 4*a*c = 16 - 4*3*5 = - 44 = - 4*11
x2 = ( - ( - 4) + 2*sqrt(-11))/(2*3) = 2/3 + (1/3)*i*sqrt(11)
x3 = 2/3 - (1/3)*i*sqrt(11)
6*x = 0, x1 = 0
3*x^2 - 4*x + 5 = 0
a = 3, b = - 4, c = 5
b^2 - 4*a*c = 16 - 4*3*5 = - 44 = - 4*11

What is 30x?
18^3 is 5832
24^2 is 576
5256 is the difference but I don't know what +30x means....
