\begin{gathered} (6x^2+7x-3)/(4x^2-9) \\ 6x^2+7x-3=(2x+3)(3x-1) \\ 4x^2-9=(2x+3)(2x-3) \\ (6x^2+7x-3)/(4x^2-9)=((2x+3)(3x-1))/((2x+3)(2x-3))=(3x-1)/(2x-3) \\ (6x^2+7x-3)/(4x^2-9)=(3x-1)/(2x-3) \\ \text{The expression }(6x^2+7x-3)/(4x^2-9)\text{ in lowest terms is }(3x-1)/(2x-3) \\ To\text{ determine when is undefined} \\ 2x-3=0 \\ 2x=3 \\ x=(3)/(2) \\ The\text{ expression is undefined when x is }(3)/(2) \end{gathered}
