Question 158003: 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-x^4 Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! Take half of the x coefficient -4 to get -2. Now square -2 to get 4. So you need to add 4 to make a perfect square trinomial.
So the answer is choice d. 4; x^2-4x+4=(x-2)^2 (note: the last part that you wrote is a typo)
