Add -4 to both sides


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x^2\ +\ 16x\ +\ 60\ =\ 0]


Factor.  Hint:  6 times 10 = 60 and 6 plus 10 = 16.


Apply the Zero Product Rule to find the two solutions.  Since the quadratic factors over the rationals, the roots are rational and exact.  That is, there is no need for a numerical approximation for a solution set element that can be represented exactly numerically.
