Solution for 11z-2/6z-7z/6z equation: 


z in (-oo:+oo)

11*z-(((7*z)/6)*z)-((2/6)*z) = 0

(-7/6)*z^2+11*z+(-1/3)*z = 0

32/3*z-7/6*z^2 = 0

DELTA = (32/3)^2-(-7/6*0*4)

DELTA = 1024/9

DELTA > 0

z = ((1024/9)^(1/2)-32/3)/(-7/6*2) or z = (-(1024/9)^(1/2)-32/3)/(-7/6*2)

z = 0 or z = 64/7

z in { 0, 64/7 }
