the answer is −3x3+11x2−7(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: 3x2−3x−x−1 then group then and factor
(3x2−3x)+(x−1) then after you factor, you get (3x+1)(x−1) then put the other equation in
