Need some help on these, just to make sure I understand what I'm doing...
1) If then
2) If then
3) solve for x
4) solve for x
would the quadratic formula be used?
I got a zero for both of these. I had to turn back in the HW sheet because he completely missed a problem and gave a zero for it and I didn't have time to think about these two at the moment.
I can't understand why I shouldn't get at least 1 point for both of the problems, even though he wanted the work shown.
