Can students see the link between factorising and solving? I love the FORMULA but I will keep Quadratic formula for later until they draw that link. Also introducing formula too quick disconnect the sense of students relating or seeing quadratic expressions on a grid re graphs. E.

In addition it is often very efficient and can be used with expressions not just equations (handy for proofs).qehs teacherhttps://www.blogger.com/profile/09586131401710055359noreply@blogger.comtag:blogger.com,1999:blog-4242439961617529545.post-26716791983006222682017-05-07T18:51:00.667+01:002017-05-07T18:51:00.667+01:00Factorising is more efficient.
