A landscape architect's designs for a town park call for two parabolic-shaped walkways. When the park is mapped on a Cartesian coordinate plane, the pathways intersect at two points. If the equations of the curves of the walkways are y = 11x? +23x + 210 and y = -19x² - 7x + 390, determine the coordinates of the two points of intersection. ​
