Question 195243
<font face="Garamond" size="+2">



Technically what you have specified are the roots of the equation *[tex \LARGE x^2-11x-12 = 0] which are also the x-coordinates of the x-intercepts of the  graph of *[tex \LARGE y = x^2-11x-12].  The x-intercepts are points in *[tex \LARGE R^2] and therefore must properly be specified as ordered pairs.  In this case (-1,0) and (12,0).
