Question 1055262: What number needs to be added to both sides of the equation in order to complete the square?
x^2+14x=−32
I'm not sure how your supposed to complete the square in the first place, so if you could explain that, it would be much appreciated

Take half the x coefficient and square it.
Add it to both sides.
In this case, it's 14.
So 14%2F2=7 and 7%5E2=49
So add 49 to both sides.
x%5E2%2B14x%2B49=-32%2B49
%28x%2B7%29%5E2=17
