This is one of five problems posted this week on Tumblr for my students to attempt
to solve. The lesson on solving quadractic has not been taught as yet. The assumption
is that some students may have remember this from their prior classes and may be
able to come up with the right answer. Hopefully it will generate a discussion among
themselves to arrive at the correct result.
One of the solutions to the quadractic equation (x-3)(x+8)= -30 is
We have invited students from other classes to participate and have gotten a few
to join in. So far ,I have seen both incorrect and correct responses to the above question.
