Factoring Review - 4

by J. Gomez

2

Look for the greatest common factor
  • If a (b + c) = ac + bc, then ac+bc = (a )(b+ c)

  • Distribution works both ways

  • If you can factor a monomial out of an expression, it will be the largest factor that is a factor of each term

  • 5x2 + 10x : 5 and 10 have a common factor of 2, and x2 and x have a common factor of x, so you can factor out 2x
