Subproblem 2
Set the factor '(22 + 9u + u2)' equal to zero and attempt to solve:

Simplifying
22 + 9u + u2 = 0

Solving
22 + 9u + u2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-22' to each side of the equation.
22 + 9u + -22 + u2 = 0 + -22

Reorder the terms:
22 + -22 + 9u + u2 = 0 + -22

Combine like terms: 22 + -22 = 0
0 + 9u + u2 = 0 + -22
9u + u2 = 0 + -22

Combine like terms: 0 + -22 = -22
9u + u2 = -22

The u term is 9u.  Take half its coefficient (4.5).
Square it (20.25) and add it to both sides.

Add '20.25' to each side of the equation.
9u + 20.25 + u2 = -22 + 20.25

Reorder the terms:
20.25 + 9u + u2 = -22 + 20.25

Combine like terms: -22 + 20.25 = -1.75
20.25 + 9u + u2 = -1.75

Factor a perfect square on the left side:
(u + 4.5)(u + 4.5) = -1.75

Can't calculate square root of the right side.
