Question 1166397:
Find the solution to the following quadratic equation using the method of completing the square
x²- 4x-12=0 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! x^2-4x=12, start by moving the constant.
take half of the b (bx), square it and add to both sides
x^2-4x+4=12+4
factor
(x-2)^2=16
take the square root of both sides
x-2=+/-4
move the constant
x=2+/-4
x=-2, 6
