The answer is 4/3 and I checked two times
do you mean 2x squared? If so, x = 5, -5
5/12 is the simplified fraction for 30/72 by using the GCD or HCF method. 5/12 is simplified fraction for 30/72 by using the prime fractorization method.
Simple,
1/2 of 60
re-write it as 0.5 of 60 aka 0.5*60
which is 0.5*60=30
Do the same with 1/2 of 24.
0.5 of 24
0.5*24=12.
Thus, it's not the same because they are different numbers and different number give you different answers.
I believe that the zeros would be -2 and -6, assuming that the first 2 that you wrote in the equation is supposed to be a power to the x.
