Hi! Let me help you! :)

  • Remember, factoring looks like so:
  • ab+ac=a(b+c)
  • In this case, a is the common term, so we factor it out.
  • Now, let's check our polynomial and see if we can spot the common term.
  • All terms are divisible by 4, so 4 is the common term.
  • 4x²-4x-8
  • x²-x-2

Answer:

x²-x-2

Hope you find it helpful.
