Solving for variable 'u'.

Begin completing the square.

Move the constant term to the right:

Add '23' to each side of the equation.
-23 + -24u + 23 + u2 = 0 + 23

Reorder the terms:
-23 + 23 + -24u + u2 = 0 + 23

Combine like terms: -23 + 23 = 0
0 + -24u + u2 = 0 + 23
-24u + u2 = 0 + 23

Combine like terms: 0 + 23 = 23
-24u + u2 = 23

The u term is -24u.  Take half its coefficient (-12).
Square it (144) and add it to both sides.

Add '144' to each side of the equation.
-24u + 144 + u2 = 23 + 144

Reorder the terms:
144 + -24u + u2 = 23 + 144

Combine like terms: 23 + 144 = 167
144 + -24u + u2 = 167

Factor a perfect square on the left side:
(u + -12)(u + -12) = 167
