Answer:

x = -5 and x = -9.

Step-by-step explanation:

To factor this, we need to find two numbers that add to 14 and multiply to 45.  These are 5 and 9.  Therefore, this equation factors to (x + 5)(x + 9) = 0.  The two x values that would make this true are -5 and -9 because they would make (x + 5) and (x + 9) equal to 0 respectively.
