Question

What number should be added to both sides of the equation to complete the square?
x-+ 3x = 6

Answer 1

Explanation:

To complete the square you divide the linear coefficient of x by 2, square it, and add that to both sides. In this case the coefficient is 3 so

(3/2)^2=9/4 or 2.25

So you would add 9/4 or 2.25 to both sides.
