Solution for x+1/2x^2-7x+6-x-3/2x^2-x-3 equation: 


x in (-oo:+oo)

(1/2)*x^2-((3/2)*x^2)+x-(7*x)-x-x-3+6 = 0

(1/2)*x^2+(-3/2)*x^2+x-7*x-x-x-3+6 = 0

3-x^2-8*x = 0

DELTA = (-8)^2-(-1*3*4)

DELTA = 76

DELTA > 0

x = (76^(1/2)+8)/(-1*2) or x = (8-76^(1/2))/(-1*2)

x = (2*19^(1/2)+8)/(-2) or x = (8-2*19^(1/2))/(-2)

x in { (2*19^(1/2)+8)/(-2), (8-2*19^(1/2))/(-2) }
