MathIsPower4U: James Sousa's "Factor by Grouping"

Watch the first 6 minutes of the video and take notes. Note the steps taken to factor a four-term polynomial.

  1. Separate the polynomial into two groups of two terms.
  2. Identify a common factor in each of the group and factor it out.
  3. Check that the resultant expressions contain a common binomial factor. If they do not, then the polynomial cannot be factored, at least not when the terms are grouped this way.
  4. Factor out a common binomial factor and rewrite the polynomial as a product of two binomials.
