To find the equation given the roots 5 and 9:

x² - (sum or the roots) + (product of the roots) = 0

x² - (5+9)x + (5)(9) = 0

x² - 14x + 45 = 0   ⇒  ANSWER (This equation has roots 5 and 9).

--------------
Check:
x² - 14x + 45 = 0

Factor ⇒ (x - 9) (x - 5) = 0
x- 9 = 0             x - 5 = 0
x = 9                 x = 5
