Solving
-24 + u + u2 = 0

Solving for variable 'u'.

Begin completing the square.

Move the constant term to the right:

Add '24' to each side of the equation.
-24 + u + 24 + u2 = 0 + 24

Reorder the terms:
-24 + 24 + u + u2 = 0 + 24

Combine like terms: -24 + 24 = 0
0 + u + u2 = 0 + 24
u + u2 = 0 + 24

Combine like terms: 0 + 24 = 24
u + u2 = 24

The u term is u.  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.
u + 0.25 + u2 = 24 + 0.25

Reorder the terms:
0.25 + u + u2 = 24 + 0.25

Combine like terms: 24 + 0.25 = 24.25
0.25 + u + u2 = 24.25

Factor a perfect square on the left side:
(u + 0.5)(u + 0.5) = 24.25
