Answer:


2x^2+1-(x)/(2x^2-3)

Explanation:

Use the long division method to divide polynomials:


\large \begin{array}{r}2x^2\phantom{)))))}+1\phantom{)}\\2x^2-3{\overline{\smash{\big)}\,4x^4-4x^2-x-3\phantom{)}}}\\\underline{-~\phantom{(}(4x^4-6x^2)\phantom{-b))))))}}\\0+2x^2-x-3\phantom{)}\\\underline{-~\phantom{()}(2x^2\phantom{))))}-3)}\\-x\phantom{))))))}\end{array}

Therefore:


(4x^4-4x^2-x-3)/(2x^2-3)=2x^2+1-(x)/(2x^2-3)
