Solution for 4x^5-16x^3-8x^2/4x^2 equation: 


x in (-oo:+oo)

4*x^5-(((8*x^2)/4)*x^2)-(16*x^3) = 0

4*x^5-2*x^4-16*x^3 = 0

4*x^5-2*x^4-16*x^3 = 0

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

2*x^2-x-8 = 0

DELTA = (-1)^2-(-8*2*4)

DELTA = 65

DELTA > 0

x = (65^(1/2)+1)/(2*2) or x = (1-65^(1/2))/(2*2)

x = (65^(1/2)+1)/4 or x = (1-65^(1/2))/4

2*x^3 = 0

2*x^3 = 0 // : 2

x^3 = 0

x = 0

x in { (1-65^(1/2))/4, (65^(1/2)+1)/4, 0 }
