the answer is (-3x^3+11x^2-7)/((3x+1)(x-1))

Explanation:

the first equation can't factor anymore so leave that alone and move on to solve the next equation. 3*-1 gives you -3 and you have to find what multiplies to gives you that and adds up to the middle number: -2. once you get that, it should look like this: 3x^2-3x-x-1 then group then and factor
(3x^2-3x)+(x-1) then after you factor, you get (3x+1)(x-1) then put the other equation in
