I fixed it because the book did not equate it to zero which it should be
Now
\(\frac{4x^3-12x^2-36x+27}{(2x-3)}=0\)
\(4x^3-12x^2-36x+27=0\)
The best approach is to use values. Algebra is a bit cumbersome
If you use 0 to see if the answer is C then we do have, substituting
\(27 >0\) So C is not possible
If we use 2
we have
\(32-48-72+27=-61<0\)
You have already two conflict answers
D is right away
