Solution for (30k^11-42k^8)/6k^5 equation: 


k in (-oo:+oo)

k^5*((30*k^11-(42*k^8))/6) = 0

k^5*((30*k^11-42*k^8)/6) = 0

(k^5*(30*k^11-42*k^8))/6 = 0

30*k^11-42*k^8 = 0

6*k^8*(5*k^3-7) = 0

5*k^3 = 7 // : 5

k^3 = 7/5

k^3 = 7/5 // ^ 1/3

k = (7/5)^(1/3)

6*k^8*(k-(7/5)^(1/3)) = 0

(6*k^5*k^8*(k-(7/5)^(1/3)))/6 = 0

( 6*k^8 )
