A solution of x^3 - 9x^2 + 15x + 25 = 0 is x = 5. How many other (distinct) solutions are there?
A) 0 B)1 C)2 D)3 E)4
What did you see when you plugged the graph into your calculator? What did you get when you divided out the given factor "x - 5" (or else plugged the given zero, x = 5, into the synthetic division) and then applied the Quadratic Formula to the remaining factor?
