Factorising tricky quadratics

Author: Melvin M Peralta

Author commentary:

Potential Areas of Discussion: This one could raise discussions about factoring quadratics and sums and products of even and odd numbers. It also brings up the question “what counts as factoring?”.  For example, does (x – 2.5)(x + 6) count?

Extensions: Change “b is even” to “b is prime”.  I haven’t thought much about it but I’m hoping it yields interesting results.
