What number must be added to both sides of the equation in order to complete the square? Please someone help..
x^2+3x=-3
1) Make certain that the coefficient of the x2 term is 1 ( it is )
2) Divide the coefficient of the x-term by 2 ( 3 divided by 2 is 3/2 )
3) Square this answer ( (3/2)2 = 9/4 )
4) Add this answer to both sides.
x2 + 3x + 9/4 = -3 + 9/4
