Set $up$ the form for the partial fraction decomposition. $Do$ not solve for $A,B,C,$ and $soon.$

$\frac{3x^2-10x+7}{3x^3+12x}$

Select one:

$A.\frac{A}{3x}+\frac{Bx+C}{x+2}+\frac{Dx+E}{x-2}$

$B.\frac{A}{3x}+\frac{Bx+C}{x^2+4}$

$C.\frac{A}{3x}+\frac{B}{x+2}+\frac{C}{x-2}$

$D.\frac{A}{3x}-\frac{Bx+C}{x^2+4}$
