Put in Format to Complete the Square:Move the number term to the right side of the equation:
x%5E%282%29-7x+=+-12
Add 49/4 to both sides
x%5E%282%29-7x+%2B49%2F4=+-12%2B49%2F4
%28x-7%2F2%29%5E%282%29=+-48%2F4+%2B+49%2F4
%28x-7%2F2%29%5E%282%29=+1%2F4
Taking the Square Root of both sides of the Equation
x-7/2 equals either 1/2 0r -1/2
x -7/2 = 1/2
x = 4
x-7/2 = -1/2
x = 3
