XS problems

[Matthew Simms]

The problems on pg. 354 A and C are different.  they are both very similar because but they are different and student who have asked for help from other students who are woking on problems start working on problem a instead of the original problem. 

 

Problem C has x-interecept of -3 and 2. 

but the parabola opens down so it can't be (x+3)(x-2)

there has to be a negative -(x+3)(x-2)

 

 

Two student I know have this problem are Zaira and Ashley O.
