G PROBLEM
multiply by g to get rid of fraction
g^3 -6g^2-55
g(g+5)(g-11)
wait is everything over g or just the 55?

triciaal · Answer

(k^ 3 + k) / (k^2 + k - 42)
k (k^2 + 1) / (k -6)(k + 7)
factors of 42 when multiplied you get a negative and when added you get +1
that's why i used -6 and +7
k  cannot be 6 or -7 because you do not want to divide by zero

everythin is over g
