Guys do not trust this account it gives you a virus

yeah he tried to get me to the link, it flagged it before I even got to the site

Step 1) Move all constants to the right side, leaving all of the terms with variables on the left side

x^2 - 12x = -28

Step 2) Find a number that would create a perfect square trinomial on the left side. For this problem, that would be 36. So, we need to add 36 to the left and right sides.

x^2 - 12x + 36 = -28 + 36

x^2 - 12x + 36 = 8

Step 3) Rewrite the perfect square trinomial on the left, so it only has two terms (becomes the square of itself)

(x - 6)^2 = 8

Step 4) Take the square root of both sides - remember that it is plus/minus because of the square!

x - 6 = ±

x - 6 = ±

Step 5) Find the two solutions of x

x = 6 +

x = -6 +

Hope this helps! :)
