Solution for 8x^3-16x^2+12/-2x equation: 


x in (-oo:+oo)

8*x^3-(16*x^2)+(12/(-2))*x = 0

8*x^3-16*x^2+(12/(-2))*x = 0

8*x^3-16*x^2-6*x = 0

2*x*(4*x^2-8*x-3) = 0

4*x^2-8*x-3 = 0

DELTA = (-8)^2-(-3*4*4)

DELTA = 112

DELTA > 0

x = (112^(1/2)+8)/(2*4) or x = (8-112^(1/2))/(2*4)

x = (4*7^(1/2)+8)/8 or x = (8-4*7^(1/2))/8

2*x = 0

2*x = 0 // : 2

x = 0

x in { (8-4*7^(1/2))/8, (4*7^(1/2)+8)/8, 0 }
