    I assume that you want to simplify this product. Unfortunately a TI84 can only calculate values using numbers. So you have to do this problem by hand (and brain of course ):

    \dfrac{24x^3}{4x^2-36} \cdot \dfrac{2x^2+6}{16x^2} = \dfrac{8x^2 \cdot 3x \cdot 2x(x+3)}{4(x+3)(x-3) \cdot 8x^2 \cdot 2}

    Cancel equal factors. As the final result I've got: \dfrac{3x^2}{4(x-3)}
