This week we learned how conjugates simplify in binomials, IE (x+4)(x-4) it will always have 2 terms and the second will be a negative constant so (x+4)(x-4) = x^2-16 and it will always be a negative perfect square on the end no matter what. These are important time savers because this will make it (if I recognize I can do it) so I can skip straight to my answer in simplifying rather than having to go through the writing it down and adding like terms and such.
