Solution for 2z^2-17z+8/2z^2+3z-2/16z^2-10z+1/8z^2+15z-2 equation: 


z in (-oo:+oo)

2*z^2+(8/2)*z^2-((2/16)*z^2)+(1/8)*z^2-(17*z)+3*z-(10*z)+15*z-2 = 0

2*z^2+(8/2)*z^2+(-1/8)*z^2+(1/8)*z^2-17*z+3*z-10*z+15*z-2 = 0

6*z^2-9*z-2 = 0

DELTA = (-9)^2-(-2*4*6)

DELTA = 129

DELTA > 0

z = (129^(1/2)+9)/(2*6) or z = (9-129^(1/2))/(2*6)

z = (129^(1/2)+9)/12 or z = (9-129^(1/2))/12

z in { (9-129^(1/2))/12, (129^(1/2)+9)/12 }
