Solution for k^2-7k-18/6k+18 equation: 


k in (-oo:+oo)

k^2-(7*k)-((18/6)*k)+18 = 0

k^2-7*k-3*k+18 = 0

k^2-10*k+18 = 0

DELTA = (-10)^2-(1*4*18)

DELTA = 28

DELTA > 0

k = (28^(1/2)+10)/(1*2) or k = (10-28^(1/2))/(1*2)

k = (2*7^(1/2)+10)/2 or k = (10-2*7^(1/2))/2

k in { (10-2*7^(1/2))/2, (2*7^(1/2)+10)/2 }
