x^2 - 14x = 7 to make it a perfect square?

OpenStudy (anonymous):

What's the question?

OpenStudy (anonymous):

What number would you have to add to both sides to complete the square? x2 – 14x = 7

OpenStudy (anonymous):

Take the coefficient of x, divide it by two, and then square that number. What you get is what you add to both sides. (-14/2)^2=?

Thank you! Please confirm +49.
