Question 166736: Determine the constant that should be added to the binomial so that it becomes a perfect square trinomial. Then write and factor the trinomial.
x^2 - 4x
a. 16; x^2 - 4x + 16 = (x - 4)^2
b. -4; x^2 - 4x - 4 = (x - 2)^2
c. -16; x^2 - 4x - 16 = (x - 4)^2
d. 4; x^2 - 4x + 4 = (x - 2)^2
