Answer:

(x - 6)(x + 1)

Explanation:

These are the factors

  • First, find the factors of 6
  • 6
  • / / \ \
  • 1 2 3 6

  • 1 and 6 make 5
  • 2 and 3 also make 5

  • But which one makes -5
  • -3+2=-1 -2+3=1
  • So not 2 and 3

  • -1+6=5 -6+1=-5
  • 1 and -6 works

This means the factors as (x - 6) and (x + 1).

Hope this helps,

Kavitha

P.S - Have an awesome day!!
