Solution for 9k^2+6k+1/9k^2-1 equation: 


k in (-oo:+oo)

9*k^2+(1/9)*k^2+6*k-1 = 0

82/9*k^2+6*k-1 = 0

DELTA = 6^2-(-1*4*82/9)

DELTA = 652/9

DELTA > 0

k = ((652/9)^(1/2)-6)/(2*82/9) or k = (-(652/9)^(1/2)-6)/(2*82/9)

k = 9/164*((652/9)^(1/2)-6) or k = -9/164*((652/9)^(1/2)+6)

k in { -9/164*((652/9)^(1/2)+6), 9/164*((652/9)^(1/2)-6) }
