Watch the first 6 minutes of the video and take notes. Note the steps taken to factor a four-term polynomial.
- Separate the polynomial into two groups of two terms.
- Identify a common factor in each of the group and factor it out.
- 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.
- Factor out a common binomial factor and rewrite the polynomial as a product of two binomials.
