Which of the following is NOT a factor of x²-5x+6?

Q: Which of the following is NOT a factor of x²-5x+6?

The correct answer is B. x²-5x+6 = (x-2)(x-3). We need two numbers that multiply to +6 and add to -5. Those are -2 and -3. So the factors are (x-2) and (x-3). Options (x+2) and (x+3) are NOT factors. Since the question asks which is NOT a factor, both B and D are correct, but B is the primary answer.
