Factoring By Grouping 1)Group the first two terms and the second two terms 2) Factor the GCF out of each pair 3) Factor out the common binomial factor.
Factoring Quadratic Trinomials When a≠1 **We can not approach this problem the same way we approach problems where a=1. We have to factor by grouping, so we need to re-write this quadratic expressions with 4 terms.
Factoring Practice **Think ahead. You know your second binomial needs to match the first. Anticipate when you need to factor out a negative.
