Add -4 to both sides



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.
