Solution for 56x^4+24x^3+56x^2/8x^3 equation: 


x in (-oo:+oo)

((56*x^2)/8)*x^3+56*x^4+24*x^3 = 0

7*x^5+56*x^4+24*x^3 = 0

x^3*(7*x^2+56*x+24) = 0

7*x^2+56*x+24 = 0

DELTA = 56^2-(4*7*24)

DELTA = 2464

DELTA > 0

x = (2464^(1/2)-56)/(2*7) or x = (-2464^(1/2)-56)/(2*7)

x = (4*154^(1/2)-56)/14 or x = (-4*154^(1/2)-56)/14

x^3 = 0

1*x^3 = 0 // : 1

x^3 = 0

x = 0

x in { (-4*154^(1/2)-56)/14, (4*154^(1/2)-56)/14, 0 }
