From the question,

We are to factorize


33x^2+2x-3

This is done as follows


\begin{gathered} 33x^2+2x-3 \\ =33x^2+11x-9x-3 \end{gathered}

This is further factorized as


\begin{gathered} 33x^2+11x-9x-3 \\ =11x(3x+1)-3(3x+1) \\ =(3x+1)(11x-3) \end{gathered}

Therefore, we have


\begin{gathered} 33x^2+2x-3 \\ =(3x+1)(11x-3) \end{gathered}
