Solution for 8x^3-10x^2-25x/4x^2+5x=0 equation: 


x in (-oo:+oo)

8*x^3-(((25*x)/4)*x^2)-(10*x^2)+5*x = 0

8*x^3+(-25/4)*x^3-10*x^2+5*x = 0

7/4*x^3-10*x^2+5*x = 0

x*(7/4*x^2-10*x+5) = 0

7/4*x^2-10*x+5 = 0

DELTA = (-10)^2-(7/4*4*5)

DELTA = 65

DELTA > 0

x = (65^(1/2)+10)/(7/4*2) or x = (10-65^(1/2))/(7/4*2)

x = 2/7*(65^(1/2)+10) or x = 2/7*(10-65^(1/2))

x = 0

x = 0

x in { 2/7*(10-65^(1/2)), 2/7*(65^(1/2)+10), 0 }
