Solution for (6/3x^2-4x-7)+(3/3x^2-19x+28) equation: 


x in (-oo:+oo)

(6/3)*x^2+(3/3)*x^2-(4*x)-(19*x)-7+28 = 0

(6/3)*x^2+(3/3)*x^2-4*x-19*x-7+28 = 0

3*x^2-23*x+21 = 0

DELTA = (-23)^2-(3*4*21)

DELTA = 277

DELTA > 0

x = (277^(1/2)+23)/(2*3) or x = (23-277^(1/2))/(2*3)

x = (277^(1/2)+23)/6 or x = (23-277^(1/2))/6

x in { (23-277^(1/2))/6, (277^(1/2)+23)/6 }
