x2 - 12x = -6
Your next step would be to add 36 to both sides.
x2 - 12x + 36 = 30
In completing the square, we divide the term before x by 2, and then square it and add it to both sides.
12 / 2 = 6
6^2 = 36
That would be the next step.

Step-by-step explanation:
the shape is a square (meaning all sides are equal)
CR = AR = CA=AT=AR=AT=RT=RS=ST=CS=4
the triangle in a square is an equilateral triangle meaning all sides are equal
the sum of angles in a triangle is 180°
all the angles in each triangle is 180/3 = 60°
the sum of angles in a square is 360
the angles at each angles ∠A =∠T=∠S= ∠C = 360/4 = 90°
