Hi guys, I'm shaming to ask this simple exercise to you all but here is it. >>
4 3 2 3
12·a - 8·a·x + 12·a·x - 18·a·x
It's a factorization, I'm trying already 10 minutes but still no result. I hope someone can solve this quickly.
_________________________________________________
Here's in a very simple and quick example of a factorization: >>
tr + 7r - st -7s = (tr - st) + (7r - 7s) (I took tr and st together)
= t.(r-s) + 7.(r-s)
= (r-s).(t+7)

Stupid and incorrect.

Thanks, I know ^
But your solution isn't correct because when I calculate this out I become:>>
Код:
12a^4 - 24a^3x - 12a^3
While it should be this: >>
Код:
12a^4 - 8ax^3 + 12ax^2 - 18ax^3
