Solution for 2x^2-5/4x=1/2 equation: 


x in (-oo:+oo)

2*x^2-((5/4)*x) = 1/2 // - 1/2

2*x^2-((5/4)*x)-(1/2) = 0

2*x^2+(-5/4)*x-1/2 = 0

2*x^2-5/4*x-1/2 = 0

DELTA = (-5/4)^2-(-1/2*2*4)

DELTA = 89/16

DELTA > 0

x = ((89/16)^(1/2)+5/4)/(2*2) or x = (5/4-(89/16)^(1/2))/(2*2)

x = ((89/16)^(1/2)+5/4)/4 or x = (5/4-(89/16)^(1/2))/4

x in { (5/4-(89/16)^(1/2))/4, ((89/16)^(1/2)+5/4)/4 }
