The way you solve the problem is by factoring using the gcf in factoring there are 3 ways of factoring finding a gcf which is the method you use for this problem , factoring, finding the square root in this case the gcf is x in the first part neg. 3 x^3 we see 3 xs but in the second we see 1 so we can divide or factor by x or 1x which would give us x parenthesis neg. 3x to the 2 minus 4 so our answer is x equals 0, 4 over 3 bec. We divide the neg. 3 by neg. 4 to get 4 over 3
