Two parabolas with a common vertex and with axes along $\displaystyle x$-axis and $\displaystyle y$-axis, respectively, intersect each other in the first quadrant. If the length of the latus rectum of each parabola is $\displaystyle 3$, then the equation of the common tangent to the two parabolas is :
