This is part 3 of factoring trinomials into 2 binomials when the coefficient of x-squared is not 1. It is a continuation of part 2 showing three more examples of using the short-cut (sneaky) method of first finding one correct factor using the product and sum.

  • Factoring Polynomials - A condensed worksheet that describes the steps to look at / think about when attempting to factor a polynomial.
  • Algebra Tiles - A website that allows you to factor trinomials visually using Algebra Tiles.
  • Is there a shortcut method for factoring a trinomial?
  • How do you factor a trinomial by finding one factor and using it to find the other factor?
  • How do you factor 6x^2 + 23x + 21?
  • How can you check to make sure that the factored form of a trinomial is correct?
  • How do you factor 9x^2 + 3x + 2?
  • What happens if you cannot factor a trinomial?
  • How do you factor 3x^2 + 22x - 16?
This lesson is a continuation of the previous lesson -- more examples of factoring trinomials by using a shortcut trick for finding one factor and then using that factor to find the second factor. Many good examples are explained step by step.
