Answer:

(x +6) (x-1)

Step-by-step explanation:

Find the factors of 6 first =  1,6 and 2,3

You must choose the set that when you add them together will make positive 5, but when you multiply them it must make a negative six since the last term is negative

So  (x +6 ) (x -1)  because if you add 6 + (-1) you get 5

and when you multiply 6 x -1 you get -6
