Which of the following is a factor of X^2
- 2x + 15

Select one
X-5
X+3
None of the above
X-3

both (x - 5) and (x - 3) are factors of x^2  - 2x + 15

Step-by-step explanation:

Please write this all on one line:  x^2  - 2x + 15.

Recognize that 3*5 = 15.  Possible factors of x^2  - 2x + 15 are thus (x - 5) and (x + 3).  Multiplying these together results in x^2  - 2x + 15, so we have verified that both (x - 5) and (x - 3) are factors of x^2  - 2x + 15.
