Answer:
Add 36 to each side
x = 6±sqrt(30)
Step-by-step explanation:
x^2−12x=−6
Take the coefficient of x
-12
Divide by 2
-12/2 = -6
Square it
(-6)^2 = 36
Add 36 to each side
x^2−12x+36=−6+36
( x-6)^2 = 30
Take the square root of each side
x-6 = ±sqrt(30)
Add 6 to each side
x-6+6 = 6±sqrt(30)
x = 6±sqrt(30)
