Begin completing the square.

Move the constant term to the right:

Add '60' to each side of the equation.
-60 + -1x + 60 + x2 = 0 + 60

Reorder the terms:
-60 + 60 + -1x + x2 = 0 + 60

Combine like terms: -60 + 60 = 0
0 + -1x + x2 = 0 + 60
-1x + x2 = 0 + 60

Combine like terms: 0 + 60 = 60
-1x + x2 = 60

The x term is -1x.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1x + 0.25 + x2 = 60 + 0.25

Reorder the terms:
0.25 + -1x + x2 = 60 + 0.25

Combine like terms: 60 + 0.25 = 60.25
0.25 + -1x + x2 = 60.25

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = 60.25
