Question

What is `(-3x^3+11x^2-7)-:(3x^2-2x-1)`?

Answer 1

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
