Use the method of completing the square to transform the quadratic equation into the equation form (x – p)2 = q.

x2 - 12x - 9 = 0
A) (x - 36)2 = 9
B) (x - 36)2 = -9
C) (x - 6)2 = 45
D) (x - 6)2 = -45

Respuesta :

x^2-12x-9=0
Add 9 to both sides
x^2-12x=9
Add (b/2)^2 to both sides
x^2-12x+36=45
Factor
(x-6)^2=45
So C is the answer
