✔ 最佳答案
x^2 + 12x +__To complete the square, take the coefficient of x (=12), divide by 2(=6) and square the number you get (=36)
x^2 + 12x + 36

x^2 + 12x + __
= x^2 + 6x + 6x + __
x^2 + 6x + 6x + __ = (x + 6)^2
x^2 + 6x + 6x + __ = (x + 6)(x + 6)
x^2 + 6x + 6x + __ = x^2 + 6x + 6x + 36
__ = 36
= x^2 + 6x + 6x + __
x^2 + 6x + 6x + __ = (x + 6)^2
x^2 + 6x + 6x + __ = (x + 6)(x + 6)
x^2 + 6x + 6x + __ = x^2 + 6x + 6x + 36
__ = 36
