Subproblem 1
Set the factor '(-5 + m + m2)' equal to zero and attempt to solve:

Simplifying
-5 + m + m2 = 0

Solving
-5 + m + m2 = 0

Begin completing the square.

Move the constant term to the right:

Add '5' to each side of the equation.
-5 + m + 5 + m2 = 0 + 5

Reorder the terms:
-5 + 5 + m + m2 = 0 + 5

Combine like terms: -5 + 5 = 0
0 + m + m2 = 0 + 5
m + m2 = 0 + 5

m + m2 = 5

The m term is m.  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.
m + 0.25 + m2 = 5 + 0.25

Reorder the terms:
0.25 + m + m2 = 5 + 0.25

Combine like terms: 5 + 0.25 = 5.25
0.25 + m + m2 = 5.25

Factor a perfect square on the left side:
(m + 0.5)(m + 0.5) = 5.25
