Answer:

C) x²-2x-15=0

Step-by-step explanation:

You could put both -3 and 5 in the equations to guess and check, but the better way is to use them to create the factors.  If -3 is a root, one of the factors must be (x+3).  If 5 is a root, the other factor must be (x-5).  

(x+3)(x-5)

x²-5x+3x-15=0

x²-2x-15=0
