Solution for 8x-4/2x^2+9x-5 equation: 


x in (-oo:+oo)

8*x-((4/2)*x^2)+9*x-5 = 0

8*x-2*x^2+9*x-5 = 0

17*x-2*x^2-5 = 0

DELTA = 17^2-(-5*(-2)*4)

DELTA = 249

DELTA > 0

x = (249^(1/2)-17)/(-2*2) or x = (-249^(1/2)-17)/(-2*2)

x = (249^(1/2)-17)/(-4) or x = (249^(1/2)+17)/4

x in { (249^(1/2)-17)/(-4), (249^(1/2)+17)/4 }
