The problem is 3x^2 - 26 + 35
(We have to factor it!)
So, I did the problem, but I'm not sure how to write the final answer. This is what my problem looks like so far:
3x^2 - 26 + 35
(3x^2-21x)-(5x+35)
3x(x-7)-5(x+7)
and this is where I have the problem. I know I need to put (3x-5) but, how do I write the other part? Do I put (x-7) or (x+7) ??
THANK YOU!

The answer to your problem is (3x-5)(x-7). The reason for this is because you can factor out (3x-5) from the first part (3x^2-21x) and then factor out (x-7) from the second part (-5x+35). What this means is that the two factors you have been able to factor out will be multiplied together to form the answer, so in this case it's (3x-5)(x-7).
