Hi All,

I got this problem and it seems like it should be straight forward, but I get the wrong answer. I listed below my reasoning. What is wrong with what I am doing? Any help would be greatly appreciated.

Let B={ }

Find < > by method of comparing coefficients.

Here is what I did.

< > =C1< > +C2< > +C3< >+C4*3

2C1=3, C1=3/2

C2-5=6 C2= 11

1/2C3-4+3= -8

1/2C3=-7

C3=-14

3C4+9+7+5=27

3C4=6

C4=2

<3/2,11, -14,2>
