If the equation $k(6x^2+3)+rx+2x^2-1=0$ and $6k(2x^2+1)+px+4x^2-2=0$ have both the roots common then the value of $2r-p$is '

$\begin{array}{l}Givenk(6x^2+3)+rx+(2x^2-1)=0--\left(1\right)\\ and6k(2x^2+1)+px+(4x^2-2)=0\\ \Rightarrow 3k(2x^2+1)+\frac{p}{2}x+(2x^2-1)=0--\left(2\right)\\ comparing\left(1\right)\&\left(2\right)\\ r=\frac{p}{2}\Rightarrow 2r-p=0\end{array}$
