Answer:
(x+5) and (x-7).
Step-by-step explanation:
The given equation is :
We need to write it in factored form.
We know that,
7×5 = 35 and 7-5 = 2
So,
Hence, the required factors are (x+5) and (x-7).
Our answer is 
Our greatest common factor, or GCF, is
, so when we factor is out, our divide each term by , we get our answer. To check this, we can multiply the back across the parenthesis and see if we get the same result as our initial question.
