Which of the following expressions CAN be equal to 0 when x^2 −16= 0 ?	Choose the correct choice:
A) x^2 − 6x + 9	B) x^2 − 4x + 3	C) x^2 − x − 2	D) x^2 − 7x + 6	E) x^2 − 5x + 4
x^2 − 16 = 0   x=-4 or x=4   Onle one choice results in a possibility of 0 when you plug in -4 or 4 for x except rest of all   x^2 − 5x + 4   Answer is x^2 − 5x + 4
