Spud has a problem. He knows that the roots of a quadratic function are
Alexia says, “Just remember when we made factors from the solutions. If you wanted
and to be the answers, you used .” Use Alexia’s idea to write the equation of a quadratic function with which Spud could start.
Hugo says, “No, no, no. You can do it that way, but that’s too complicated. I think you just start with
and work backwards. So , then, hmmm… Yeah, that’ll work.” Try Hugo’s method.
Whose method do you think Spud should use? Explain your choice.
