$\frac{2 x^{4}-15 x^{2}-27}{3 x^{2}-9 x^{2}+4 x-1}$

Step 1 ：\(\frac{2 x^{4}-15 x^{2}-27}{3 x^{2}-9 x^{2}+4 x-1}=\frac{2 x^{4}-15 x^{2}-27}{-6 x^{2}+4 x-1}\)

Step 2 ：\(\text{Since there is no specific value for }x\text{, we cannot simplify further or evaluate the expression.}\)

Step 3 ：\(\boxed{\frac{2 x^{4}-15 x^{2}-27}{-6 x^{2}+4 x-1}}\)
