Solution for (9x^2/4x)-(85/4x)=-(9/4x) equation: 


x in (-oo:+oo)

x*((9*x^2)/4)-((85/4)*x) = -((9/4)*x) // + (9/4)*x

x*((9*x^2)/4)-((85/4)*x)+(9/4)*x = 0

x*((9*x^2)/4)+(-85/4)*x+(9/4)*x = 0

9/4*x^3-19*x = 0

x*(9/4*x^2-19) = 0

9/4*x^2 = 19 // : 9/4

x^2 = 76/9

x^2 = 76/9 // ^ 1/2

abs(x) = (76/9)^(1/2)

x = (76/9)^(1/2) or x = -(76/9)^(1/2)

x = 0

x = 0

x in { (76/9)^(1/2), -(76/9)^(1/2), 0 }
