What number must be added to the polynomial to complete the square? Use the slash mark ( / ) as a fraction bar if necessary.x2 +
x
1 answer:
X does not equal one but there is 1x in the problem so it is 1.
So.. to complete the square you always take 1/2 of that number.
so
half of 1 is 1/2.
Then you square that number 1/2 * 1/2 = 1/4
