Solution for 5x^2-3/6x^2-x-2 equation: 


x in (-oo:+oo)

5*x^2-((3/6)*x^2)-x-2 = 0

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

9/2*x^2-x-2 = 0

DELTA = (-1)^2-(-2*4*9/2)

DELTA = 37

DELTA > 0

x = (37^(1/2)+1)/(2*9/2) or x = (1-37^(1/2))/(2*9/2)

x = (37^(1/2)+1)/9 or x = (1-37^(1/2))/9

x in { (1-37^(1/2))/9, (37^(1/2)+1)/9 }
